The new medium-pressure Q155 Series Quintuplex sealless pumps (photo) are designed for a variety of applications, including reverse osmosis in water and wastewater treatment, mine dewatering, saltwater disposal or injection, bulk transfer, hydraulic lift and steam generation. The Q155 medium-pressure product line includes two models: Q155K, which has a maximum flowrate of 295 L/min and a maximum discharge pressure of 3,000 psi; and Q155M, which has a maximum flowrate of 246 L/min and a maximum discharge pressure of 3,500 psi. The patented sealless pumps employ hydraulically balanced diaphragms that enable the pump to handle high pressures with low stress and pump hot, abrasive fluids. The sealless design eliminates the environmental concerns of packed plunger pumps, and the multiple-diaphragm design provides virtually pulse-free, linear flow, says the company. — Wanner Engineering, Inc., Minneapolis, Minn.
