Seal-less pumps in a larger capacity
The new Hydra-Cell Q330 Series pumps (photo) feature a seal-less design to avoid the maintenance problems of mechanical or dynamic seals and packing that can leak and wear. They are designed for a variety of high-capacity applications, including saltwater disposal (SWD), saltwater injection, bulk transfer and hydraulic lift in oil fields, as well as steam generation, reverse osmosis in water and wastewater treatment, mine dewatering, boiler feed and high-pressure cleaning. Models are available to meet API 674 performance standards, the company states. The new Q330 medium-pressure models offer flowrates up to 153 gal/min and a maximum pressure rating of 3,500 psi. New high-pressure models offer flowrates up to 118 gal/min and a maximum pressure rating of 4,500 psi. Hydra-Cell Q330 Series pumps can run dry without damage, will operate with a closed or blocked suction line, and can pump hot abrasive fluids effectively. The patented, seal-less Hydra-Cell Q330 Series pumps employ hydraulically-balanced, multiple diaphragms that enable the pump to handle high pressures with low stress and abrasive particulate matter up to 800µm in size. — Wanner Engineering, Inc., Minneapolis, Minn.
