The new Q155 Series Quintuplex seal-less pumps (medium pressure models) are designed for a variety of applications including reverse osmosis in water and wastewater treatment, bulk transfer, hydraulic lift, and steam generation. The medium pressure line includes two models: Q155K, with a maximum flow rate of 78 gpm (295 l/min) and maximum discharge pressure of 3,000 psi (207 bar); and Q155M, with a maximum flow rate of 65 gpm (246 l/min) and maximum discharge pressure of 3500 psi (241 bar).
The new pumps are reportedly “packing-free” and designed to replace horizontal centrifugal pumps and packed plunger pumps, according to Wanner Engineering. Featuring a seal-less, multiple-diaphragm design, Q155 pumps can eliminate hazardous VOC emissions and clean-up and disposal costs of packed-pump leakage. The design may also eliminate the need for external lubrication and maintenance as well as plunger wear problems associated with packing.
