This metering pump exceeds API 675 standards
The Hydra-Cell Metering Solutions model MT8 triplex metering pump (photo) is designed to handle a variety of processing fluids at low flowrates and high pressures. It features a multiple-diaphragm design to provide virtually pulse-free flow without the need for pulsation dampeners. The new MT8 pump exceeds API 675 performance standards for steady-state accuracy (±1%), linearity (±3%) and repeatability (±3%), the company states. Flow capacity for the MT8 ranges from a minimum of 0.06 gal/h to a maximum of 8.0 gal/h, with discharge pressure ratings up to 3,500 psi (241 bars), depending on flow. The integral relief valve protects the pump from overpressurization on the discharge side. The replenishment valve system in every piston ensures optimum actuating oil on every stroke for continuous accuracy and protects the pump from damage in the event of blocked suction. — Wanner Engineering, Inc., Minneapolis, Minn.
