Product details

The 1250l Cat 5 pressure booster set and storage tank is designed to boost pressure in large garden irrigation systems, the pressure booster set will store a buffer of water, provide compliance with the UK Water Regulations and boost the pressure. It is ideal for lawns that require watering with pop-up sprinklers.

The submersible pump is built into the 1250l tank allowing easy installation and also quiet running. Two pump options are available for maximum flexibility. The built in tank overflow ensures that the irrigation system is separated from the mains water supply in accordance with the Water Regulations. By holding a 1250l buffer of water the irrigation system can operate for a period of time with flows that are higher than the water flow from the main tap – ideal for larger lawns sprinklers which are quite thirsty. The pump also provides a pressure of up to 6 bar, again ideal for larger lawn sprinkler systems.

The pump is designed to automatically operate when it detects a drop in pressure. To protect the pump, in the event of the tank running out of water, the pump will stop running, periodically checking to see if the tank has refilled.

Installation of the 1250l pressure booster set and storage tank set is simple. The tank requires a firm, level site and needs power and water. The unit is designed to be delivered on a pallet direct to the customer.

UK Water Regulation Compliance

Category 5 backflow is achieved using an approved Type AB air gap. As part of the specification for type AB air gaps, any overflow water must flow freely through the weirs in the tank. This must be taken into consideration when siting the unit.

Dimensions: 1200mm diameter x 1200mm high. Inlet: 3/4″ BSPM    Outlet: 1″ BSPF

Max Inlet flow: 1,400 l/h – achievable inlet flow is dependent on available incoming water flow and pressure. Tank capacity will be reduced due to the air gap.

DAB Pump output: 4,200 l/h @ 2 bar; 3,000 l/h @ 3 bar; 1,400 l/h @ 4 bar

DAB Variable Speed Pump output: 5,750 l/h @ 2 bar; 5,100 l/h @ 3 bar; 4,500 l/h @ 4 bar; 3,750 l/h @ 5 bar

Please note: Bulky items with tanks attract an additional carriage charge outside central England and into central London.
