Cold-water booster sets

Fixed- and variable-speed multi-pump booster sets from Armstrong Holden Brooke Pullen are designed for a wide range of cold-water applications. The variable-speed Hydropak IVS is available with two to four equal-sized pumps with individual ratings from 550 W to 7.5 kW. Flow rates up to 70 l/s and pressures up to 15 bar are standard. Larger pumps are available on specific designs. A display provides information on system conditions. Fixed-speed Hydropak HM sets are available with a wide range of WRAS-approved hydraulic accumulators which can be selected to recover pump energy and reduce running costs. Each set has an electronic controller for pressure-controlled boosting of up to four pumps. EEF2 motors are fitted as standard. Higher—efficiency EEF1 motors can be specified, which qualify for Enhanced Capital Allowances. All sets are factory configured and tested hydraulically, electrically and functionally before despatch.
