Hydraulic actuated diaphragm metering pump
max. 7.8 gph, max. 3 000 psig | Wilroy™ series Williams Milton Roy

Williams and Milton Roy have combined technologies to design a pump, blending the proven mRoy® hydraulic by-pass diaphragm design with the Williams "V" Series pump. The result is the low volume, high turndown characteristics of a pneumatic drive coupled with the chemical containment and high pressure capabilities of a hydraulically actuated diaphragm.
The WilRoy is a hydraulically actuated diaphragm pump which delivers chemical containment, low maintenance and overpressurization protection with unsurpassed accuracy and repeatability.
