Wanner introduces Q155 series Quintuplex pumps

Minnesota-based Wanner Engineering, Inc. has introduced its new Q155 Series Quintuplex seal-less pumps (low pressure models) designed for a variety of applications including Reverse Osmosis in water and wastewater treatment, mine dewatering, salt water disposal, salt water injection, bulk transfer, hydraulic lift and steam generation. The Q155 Low Pressure line includes three models: Q155E with a maximum flow rate of 157 gpm (595 l/min) and maximum discharge pressure of 1500 psi (103 bar); Q155F with a maximum flow rate of 127 gpm (490 l/min) and maximum discharge pressure of 1850 psi (127 bar); and the Q155H with a maximum flow rate of 111 gpm (421 l/min) and maximum discharge pressure of 2100 psi (144 bar).

New Hydra-Cell Q155 Series pumps are “packing-free” and designed to replace horizontal centrifugal pumps and packed plunger pumps in oil and gas applications, according to Wanner Engineering. Featuring a seal-less, multiple-diaphragm design, Q155 pumps eliminate hazardous VOC emissions and clean-up and disposal costs of packed-pump leakage. The design also eliminates the need for external lubrication and maintenance as well as plunger wear problems associated with packing. In addition to zero leakage, Q155 Series pumps can run dry without damage, will operate with a closed or blocked suction line and can pump abrasive fluids effectively. These performance features enable the Q155 pumps to compete with conventional plunger pumps by offering a lower cost of ownership, reducing maintenance needs, and providing a longer service life, the company states.

The patented, seal-less Hydra-Cell Q155 Series pumps employ hydraulically-balanced diaphragms that enable the pump to handle high pressures with low stress and pump hot, abrasive fluids, the company says. The seal-less design eliminates the environmental concerns of packed plunger pumps and the multiple-diaphragm design provides virtually pulse-free, linear flow.
