- Established 1975
- Trusted by thousands of customers
The Powertank GRP Industrial 2000L Twin Variable Speed Water Booster is a complete packaged boosting system for commercial and industrial premises whose mains supply cannot meet peak demand. A 2000 litre Powertank pairs with a 1.5 kW pump delivering 160 L/min at up to 3 bar.
Two inverter-driven pumps operate in duty/assist mode, doubling flow under peak load to 160 L/min while built-in redundancy keeps the system online if one pump needs servicing.
Delivered as a single ready-to-install unit with tank, pump, controller and removable unions. Made in Britain with typical 5–7 day delivery.
More about this product
The Powertank GRP Industrial 2000L Variable Speed Twin Pump is a commercial-grade boosted storage system built around a WRAS-approved insulating GRP tank with removable lid, fitted out in-house and customisable to the site. Ideal for plant rooms supplying offices, hotels, retail, factories and other commercial premises whose mains supply cannot meet peak demand.
About the Powertank Industrial Range
The Powertank GRP Industrial range is engineered to deliver water to commercial and industrial properties where mains supply is inadequate. The tank is WRAS approved and manufactured from insulating GRP, with a removable lid that makes it ideal for plant rooms. Fitted as standard with a variable speed controller and AF air gap. Each tank is built up in-house and is fully customisable to the site.
About This Build
This is the Twin Variable Speed build of the GRP Industrial range. Two inverter-driven 0.75 kW pumps (1.5 kW total) operate in duty/assist mode, delivering up to 160 L/min. Under normal load a single pump runs; when demand exceeds its capacity the second pump cuts in automatically. The pumps also alternate to even out wear and provide installed redundancy — if one pump needs servicing the system stays online.

What is a mains pressure boosting system?
A mains pressure boosting system increases the pressure and flow of water from the incoming mains supply into a property. It typically combines a pump and a storage or expansion tank, drawing water from the mains and delivering it to taps, showers and appliances at a stronger, more consistent pressure. They are used where the incoming mains is too weak to serve modern outlets reliably.
When do I need a mains booster pump?
You normally need a mains booster if static mains pressure is below 1.5 to 2 bar, if showers run weakly when other taps are open, or if combi boilers struggle to deliver hot water. Anglian Pumping recommends checking static pressure at the stop tap before specifying a system, then choosing a model rated for the number of bathrooms and outlets in the property.
What size mains booster do I need for my home?
Sizing depends on the number of bathrooms, the type of fittings and the static mains pressure. As a guide, a 1 to 2 bathroom property with combi boiler or single shower often needs 1.6 to 3 bar boost. A 2 to 3 bathroom property typically needs 3 to 4.5 bar with an integral break tank. Larger homes need a tank-and-pump system such as the DAB Esybox with Esytank or a Powertank set.
What is a water booster pump?
A water booster pump increases the pressure of an existing water supply to give stronger flow at taps, showers and appliances. It can be a small inline pump fitted to the incoming mains, or a larger pump and tank set that draws from a break tank to feed the whole house. Boosters do not create water – they raise the pressure of the water already coming in.
What is the difference between an inline booster and a tank-and-pump booster?
An inline booster connects straight onto the incoming mains and is limited to 12 litres per minute under UK water regulations – examples include the Salamander HomeBoost and WaterBoost WB-Compact. A tank-and-pump booster, such as the Grundfos Home Booster or DAB Esybox with Esytank, draws from a break tank and can deliver much higher flow rates for larger homes with multiple bathrooms.
What is a variable speed booster pump?
A variable speed booster uses an inverter to adjust pump speed in real time to match demand. It maintains constant pressure as outlets open and close, runs more quietly than a fixed-speed pump and typically saves up to 50 per cent of the energy a fixed-speed equivalent would use. The DAB Esybox, DAB Esybox Mini 3 and Grundfos Scala2 are common variable speed examples.
