Diaphragm Dosing Pump

The Williams "LD" Series pneumatic metering pumps are engineered for PERFORMANCE, QUALITY, SAFETY and SIMPLICITY.

Wilroy Hydraulically Actuated Diaphragm

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.
