Sports Field Irrigation

PJ Dore & Co specialise in the installation of sports field irrigation systems from two of the world leaders in this industry, Bauer and Briggs.

Bauer

The Bauer Autorain and Rainboy irrigators are reel based systems that come in various sizes to suit your specific requirements. To operate the system the reel is placed in position at one end of the field and the hose is pulled out to the other end of the field. The end of the hose is attached to the sprayer head on wheels.

The water pressure from the pumping system powers the reel and it rotates gradually drawing in the sprayer head along the full length of the field. The Bauer Autorain and Rainboy systems provide an even and efficient distribution of water to encourage optimum grass cover and growth.

The water application rate and the speed of the machine are easily altered and controlled. The winding mechanism ensures careful and precise reeling in of the hose time after time. At the end of it’s run the Bauer systems automatically switch off. The reel is then relocated for another run.

Briggs Rotorainer

The Briggs range of irrigation systems will have a model to suit your requirements. PJ Dore & Co. will advise you as to which will best suit your needs.

The Briggs Rotorainer provides an extremely efficient method of sports field irrigation. The rotorainer is placed at one end of the field and a light but durable wire rope is run to the other end of the field. The trailing hose which is attached to the back of the Rotorainer provides a high pressure water supply to the machine.

The Briggs Rotorainer operates from the water pressure generated by the pumping system. The revolving boom arms drive a toothed drum which pulls the machine along a wire rope.

This provides an even and efficient distribution of water.Once the machine reaches a predetermined point along the wire rope it automatically switches off.

The machine can be folded into a very compact size for transportation between sites.

PJ Dore & Co. provide an expert service including the installation of the water reservoirs, pumping stations and the irrigation machines themselves.

The best athletes deserve the best playing surface.

Race Course Irrigation

Briggs

The Briggs Racecourse Irrigator has been developed specifically for the demands of the modern Racing World and has been introduced on many courses both here in the UK and around the world.

Accurate and uniform application across the width and length of the track are essential to provide even going and keep the turf in top condition. With the Briggs Racecourse Irrigation package this is possible in all but the worst of weather conditions. A drive system has been developed to apply very high flow rates at very high speed so that the track can be watered as quickly as possible. The independent drive system also means that the machine can be used on most racecourses without any modification to pumps or underground mains.

Hosereels and booms are all simple to set up and transport making moving to and from the course quick and easy. The boom is lifted hydraulically on to the hosereel at the end of irrigation with no lifting or carrying involved. The unit can then be towed with a small tractor. Both the hosereels and booms are supplied with low ground pressure wheels to avoid damage to the course.

Even jumps can be cleared with ease using a hydraulic lift system designed for the purpose. This makes irrigation of landings and take off points simple and accurate.

Bends can be negotiated using bend pegs (shown left) designed specifically for continuous irrigation around the course.

Other advantages of using the Briggs Racecourse Irrigator are as follows:
- The machine is always working on dry ground
- Very low losses to wind drift due to the controlled droplet size
- Application rate can be varied between 1-35mm
- Control panel indicates run speed and shuts down the machine in the event of a problem
- All outlets have a ball valve allowing the irrigated width to be as narrow as 4m if required
- All outlets are pressure regulated to 10 psi ensuring even flow through all nozzles
- Nozzle packages can be supplied to apply varying amounts across the width of the track

Booster Pumps

A Booster pump is an electric submersible pump located in buffer tank. Controlled by pressure or flow sensor. Provides pressure in domestic water or irrigation system.

Here at PJ Dore we have high quality Booster Pumps in stock, contact us today for more information.

Booster pumps are used in applications where the normal system pressure is low and needs to be increased. Priming introduces fluid into the pumping chamber to create the pressure differential needed for pumping at a rated service. Self-priming pumps create and maintain a sufficient vacuum level to draw fluid into an inlet with no external assistance. Typically, booster pumps are used in water systems or applications that have low contamination. They have a variety of commercial, municipal, and military applications and are used in a range of industries that includes aerospace, mining, and food processing.

Booster pumps can transport different types of media. Some booster pumps use abrasive, acidic, corrosive, combustible, or hazardous materials. Others use wastewater, salt water, sewage, sludge, ash, or rendering wastes from food processing. Liquids, liquids with solids (slurry), and liquid metal are also used to increase system pressure. Depending on the application, other media used include gasoline, diesel fuel, oil, lubricants, chemicals, and coolants.

Booster pumps are made of aluminum, brass, bronze, cast iron, plastic, or stainless steel. Power sources include AC or DC voltage; pneumatic or hydraulic systems; gasoline, diesel fuel, or natural gas; steam or water; and solar power. Booster pumps include a pump stator / rotor assembly that is mounted either vertically or horizontally, depending on the orientation of the media. Close-coupled pumps mount the pump end on the motor shaft. Frame-mounted pumps mount the pump end on a bearing frame that is coupled to the motor.

Booster pumps provide a variety of optional features. Some include thermal overload protection or are rated to run continuously. Others are self-priming or can operate without pumped fluid or external lubrication for an extended period of time. Multi-stage pumps move compressed fluid from an initial stage to successive chambers or stages of pressurization in order to generate higher levels of pressure than are possible with single- stage pumping. Typically, both single-stage and multi-stage pumps have a pressure gage.

Pond Pumps

Features such as waterfalls, streams and fountains add a whole new dimension to a garden or fish pond. All of these features require a pond pump to function correctly. There are numerous types of garden pond pumps available on the market. Selecting the right pond pump involves far more than finding a brand name or a good deal on the price. There will be some math involved in this process and one must also ensure that their safety is properly considered. After all, installing a garden pond pump means installing an electrical device in water which can be very dangerous if done incorrectly. Here at PJ Dore we would be more than happy to help you select the appropriate pond pump for your project, contact us today for more information. 12v pump

Centrifugal Pumps

Here at PJ Dore & Co we have a large selection of high quality Centrifugal Pumps. Please contact us for more information.

A centrifugal pump is a rotodynamic pump that uses a rotating impeller to increase the pressure of a fluid. Centrifugal pumps are commonly used to move liquids through a piping system. The fluid enters the pump impeller along or near to the rotating axis and is accelerated by the impeller, flowing radially outward into a diffuser or volute chamber (casing), from where it exits into the downstream piping system. Centrifugal pumps are used for large discharge through smaller heads.

A centrifugal pump works by converting kinetic energy into potential energy measurable as static fluid pressure at the outlet of the pump. This action is described by Bernoulli’s principle.

With the mechanical action of an electric motor or similar, the rotation of the pump impeller imparts kinetic energy to the fluid through centrifugal force. The fluid is drawn from the inlet piping into the impeller intake eye and is accelerated outwards through the impeller vanes to the volute and outlet piping.

As the fluid exits the impeller, if the outlet piping is too high to allow flow, the fluid kinetic energy is converted into static pressure. If the outlet piping is open at a lower level, the fluid will be released at greater speed.

Submersible Pumps

A submersible pump is a pump that is able to be placed underwater and still carry out its intended purpose. Some pumps may be designed to work while being fully submerged, whereas others may be submerged or placed in a dry area. It is important to understand what type of pump you are dealing with in order that no damage is incurred when it is being used.

Submersible pump types include sump pumps and sewage pumps. These are the types with which most residential users will be most familiar. However, the submersible pump can be used in a number of other applications as well such as well pumps, fountain pumps and borehole pumps.

Submersible Water Pumps

Submersible water pumps work by protecting their motors from the liquid being pumped. Usually, the motors are placed in a water tight compartment filled with oil. Most motors used in submersible pumps are electric, either running on alternating current or direct current.

The advantages of a submersible water pumps are numerous. First, it has the advantage of being self-primed because the substance it is pumping, usually water, is right there at the pump itself. Further, the submersible pump may actually have to do less work than a standard pump simply because it is closer to the liquid being pumped.

There are some disadvantages to submersible pumps as well. There is the chance the pump will become corroded and lose its seals, thus allowing liquid to penetrate into the motor housing and causing substantial damage to the unit. Also, because these pumps are under water a good portion of their lives, accessing the pump for repairs may be difficult.

In home uses, most of these problems are somewhat diminished. A submersible pump in a home may not be submerged most of the time. If it is, it may not be completely submerged. Even so, the pump should still be easily accessed.

When choosing a submersible pump for home use, many are suited for specific tasks. Some may be better able to handle solids and would therefore make good sewage pumps. Other standard sump pumps may be simply suited for removing water from unwanted areas.

Well Pumps

A well pump is a pump that uses suction and pressure to produce something from a well, usually a liquid substance. The most common types of well pumps are those that are used for water wells and oil wells. For the home user, the most common well pump used will be a water well pump. Well Pumps

Well pumps come in various sizes. Residential well pumps may have less than one horsepower of energy in order to produce water. However, a commercial well pump often will contribute, along with other pumps, to supplying water for the entire community. Therefore, much more power will be needed.

Most current pumps are powered by electricity. However, there may times when there is no electricity or maybe a time when the well pump was installed before a point when there was electricity. A hand well pump is then needed to bring the water up from underground. In most cases, if they haven’t been used for a significant period of time, they will require priming.

An electric well pump will often not require priming even after being dormant for comparable periods of time. However, when they are first installed, an electric well pump may need to be primed. This consists of simply using a hose to pour water down the well until water starts coming up on its own.

Water Well Pumps

While a well pump may be a good tool to have when water is not available any other way, those using well water should be careful. Many choose to install filters on the line running into the home if the water is to be used for human consumption. While the underground water is usually pure, contaminants may infiltrate the pipe system, thus causing unsafe drinking water. Installing filters or neutralizing any bacteria in the water can help prevent medical problems. City water prevents this problem by using chlorine and other additives.
