High horsepower pumps

Achieving flow rates of up to 595 lpm and pressures up to 241 bar, the pumps have low NPSH requirements, allowing for operation with a vacuum condition on the suction - positive suction pressure is not necessary.

Hydra-Cell Q155 Series pumps can operate with a closed or blocked suction line and run dry indefinitely without damage, eliminating downtime and repair costs. The diaphragm design is said to handle solids up to 800 microns along with the minute abrasive particles that cause wear in gear, screw or plunger pumps while the compact design and double-ended shaft provide a variety of installation options.

Having five diaphragms in a single pump head gives pulseless flow and Wanner says tests suggest that these pumps are able to handle shear sensitive liquids better than rotary positive displacement pumps.
