Wanner Engineering Inc. has released its new Hydra-Cell T200 Series medium-pressure pumps. They feature a seal-less design that avoids the maintenance problems of mechanical or dynamic seals and packing that can leak and wear, a press release stated. With flow rates up to 95 gpm (359 l/min; 3,258 bbl/d) and a maximum pressure rating of 3,500 psi, Hydra-Cell T200 models are ideal for a variety of high-capacity applications including saltwater disposal, 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. The seal-less design means that Hydra-Cell T200 pumps do not have a leak path and therefore eliminate hazardous volatile organic compound emissions and the cleanup 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. Hydra-Cell T200 Series pumps can run dry without damage, will operate with a closed or blocked suction line and can pump hot abrasive fluids effectively. The Hydra-Cell T200 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 μ in size.
