CVRD Our CVRD (Compact Vertical Ram Duplex) range delivers the same pumping pressure as the CVR with two sludge rams that can deliver twice the flow at a more laminar flow. One sludge ram lifts as the other is pushing down, giving a more time efficient flow. The CVRD range has a flow rate up to 900 litres per minute and discharge pressures up to 5 Bar. The CVRD range is suitable for numerous applications including PST de- sludge, Sludge Transfer, Digester Feed, Grit Removal, and Food Waste. Our CVRDs can create a suction vacuum of up to 0.85 bar – the equivalent to
8.5 metres static suction lift. Our CVRD range comprises:
• CVRD200 • CVRD300
CVR The CVR (Compact Vertical Ram) is the smallest of all our pump range but one of the most popular for projects where high pressures or flows are not required. Primarily used for to de-sludge primary settlement tanks and also on grit removal applications. They have a flow rate of up to 140 litres per minute and discharge pressures up to 4 Bar. Our CVRs can create a suction vacuum of up to 0.85 bar – the equivalent to 8.5 metres static suction lift. The CVR is an ideal choice for: • Suction of sludge up to 10% dry solids
• Flow rate of 140 litres per minute • Energy efficiency and monitoring • Slow speed operation
