These seal-less pumps can handle a wide viscosity range
Wanner Engineering
The Hydra-Cell Model P200 metering pump (photo) features capabilities for metering, injecting, blending, dosing, filling, adding and mixing virtually any low-to high-viscosity fluid to be pumped into a chemical-feed processing system. The pump is seal-less, has a multiple-diaphragm design, a replenishment valve in every piston, is spring-loaded and has horizontal-disk check valves. The pump also includes new gearbox reducers, variable-frequency and drive-electronic flow adjustment. Model P200 pumps offer accurate flow throughout the entire turndown range, with virtually pulse-free linear flow. Booth 612 — Wanner Engineering, Inc., Minneapolis, Minn.
