Sprinklers, Rainguns etc.

Sprinkler irrigation is a method of applying irrigation water in a similar way to natural rainfall. Water is pumped through a system of of pumps, valves and pipes and is then sprayed into the air through sprinklers so that it breaks up into small water drops which fall to the ground. An irrigation sprinkler is used to irrigate agricultural crops, lawns, landscapes, golf courses, and other areas and can also be used for cooling and for the control of airborne dust.

Irrigation sprinklers are either buried in the ground along with their supporting plumbing, above ground or as moving sprinklers. Most irrigation sprinklers operate through electric and hydraulic technology and are grouped together in zones that can be collectively turned on and off by actuating a solenoid-controlled valve. Higher pressure sprinklers that themselves move in a circle are driven by a ball drive, gear drive, or impact mechanism (impact sprinklers) and can be designed to rotate in a full or partial circle.

The Rain Gun is a large area Sprinkler generally replacing 8 to 15 sprinklers depending on the model chosen, reducing labour requirement in shifting the sprinklers in the area. Rain Guns also gives the option to use as Auto Full or Part circle rotation with droplet size management mechanism for optimum working under windy conditions.

Pumps For Irrigation

Irrigation pumps are used to boost water through pipework to provide sufficient pressure to operate the irrigation system correctly. They can be installed in water storage tanks, rainwater harvesters, and can also be used to draw water from lakes, wells and boreholes.

Types of Irrigation Pumps

The type of pumps used in irrigation facilities are classified according to the power source required and we can advise on the best pump for your particular requirements.

Engine Driven Pumps:

For small systems petrol engine units are available with larger systems being driven by diesel engines, these can be coupled with controllers to automatically stop and start the engine as required.

Electric Pumps:

Can be powered by single-phase electric motor (230v) or three phase (400v), depending on the power available and can be surface mounted or submersible.

  • Surface Pumps: Can only be used when the water is less than 7m below the suction inlet of the pump and usually incorporate several impellers and can either be horizontal or vertical.
  • Submersible Pumps: Used when the water is to far down for a surface pump – submersible pumps are usually more efficient as all their energy is used to pressurise the water. Pumps can be installed in:
    • Wells or boreholes
    • Rivers or streams
    • Floating inlakes and reservoirs

Repairs

Repairs – we’re there to help quickly and without fuss.

Many properties in areas with high water tables extract water from the ground to provide a drinking water supply or water for irrigation purposes, In addition, low lying properties require pump systems to lift their effluent into the water company’s foul sewer systems.

All of these systems can cause a major problem if they are not working efficiently or overflowing.

At Allsebrook, we have many years of dealing with the emergencies that can occur when pump systems fail and we prioritise those problems that mean a property has no water supply or effluent is overflowing a chamber. Our engineers have the experience to troubleshoot problems and come up with a solution quickly and efficiently.

Our engineers transport a huge array of pumping equipment and accessories on their vans and can carry out repairs and maintenance on most makes of water pump on the spot. After diagnosing your pump issue, we’ll assess if the pump can be repaired or if it needs to be replaced.

Our services include:

  • Pump and Installation Inspection & Report
  • Pump Repairs
  • New pump installation
  • Pipework repairs and modification
  • Controls testing and repairs
  • System Evaluation and upgrade proposals

We also offer a call-out service for emergencies. 

Commissioning

Commissioning and how to ensure trouble-free operation

Commissioning is the process of assuring that all systems and components of a pump or pump system is installed and tested according to the operational requirements of the owner or final client. Commissioning engineers are engaged in the testing of facilities, equipment and plants to make sure they function correctly and produce the expected results.

To achieve the perfect system balance and ensure that you get the required performance levels from your pump solution, it is important to get the pump(s) correctly commissioned. Through pre-operational checks and close monitoring of all equipment, our commissioning services implement the stable and secure operation of pumping equipment. Our installation services take the guesswork out of integrating a new pump into an existing system or installing a new pump from scratch.

During commissioning we will check the pumps, the installation, the control equipment, and the total pump performance. Our highly skilled engineers combine product knowledge gained over many years with an understanding of a wide variety of applications and an in-depth experience of working with them. We will ensure that your pumping solutions are perfectly integrated into your system and will function optimally.

Overall measures for fault-free operation

  • Checking the pumps and their accessories to ensure that everything has been included in the delivery and that no damage has occurred in transit.
  • Getting the pumps ready for operation
  • Checking all the equipment installed for the purpose of protecting the pumps
  • Instructing the customer’s personnel regarding the functions and handling of the pumps and/or systems
