The WILROY metering pump is a unique blend of Williams and Milton Roy pump technology utilizing the best features from both designs to create a new robust pump with unique features and proven technology.

“V” Series Pumps are a line of Pneumatic Metering Pumps that range from 0.07 gph to 9 gph (0.27 lph to 34 lph) and pressures up to 13,100 psig (903 barg).

The pneumatic diaphragm metering pump consists of a liquid chamber and an air chamber separated by a diaphragm.

The Williams Solar Chemical Injection Pump (SCIP), previously known as the Solaroy®, is a highly efficient DC-powered injection pump operated by 12 or 24 VDC power.

The Williams “W” Series Pumps are a packed plunger design capable of flows up to 90 gallons per hour (336 liters per hour) and pressures to 2500 psig (172.36 barg).

The MK-II Oscillamatic Controller is a pneumatic pulser/timer used to operate the Williams series of pneumatically operated pumps.

The Williams Pneumatic Relays ensure proper air or gas flow rates for a given application

LINC Level Controls can activate alarms, provide a switch input for control systems, or perform a variety of desired switch operations actuated by a liquid or liquid interface
