Wanner Engineering, Inc. introduces its new Hydra-Cell Q330 Series pumps featuring 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 flow rates up to 153 gpm (579 l/min; 5247 BPD) and a maximum pressure rating of 3500 psi (241 bar). New high-pressure models offer flow rates up to 118 gpm (446 l/min; 4047 BPD) and a maximum pressure rating of 4500 psi (310 bar).
The seal-less design means that Hydra-Cell Q330 pumps do not have a leak path and therefore eliminate hazardous VOC emissions and the clean-up and disposal costs of packed-pump leakage. This also eliminates the need for external lubrication and maintenance as well as plunger wear problems associated with packing, Wanner Engineering states.
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 process abrasive particulates up to 800 microns in size, according to the company.
