Williams pneumatic metering pumps are utilized in all industries to accurately control the injection of chemicals. |
Williams MIlton Roy pneumatic pumps are used in all aspects of chemical dosing on both on-shore and off-shore applications.We stock all models manufactured by Williams Instruments as well as the spare parts for repairing units. When used for in the industries dealing with Natural Gas, LPG & LNG, Williams units are used for the metering of corrosion inhibitors for instrument protection, methanol to prevent freezing, and odorant injection for public safety. The Off-shore industry uses the Williams pneumatic pumps for the metering of Oil and Gas corrosion inhibitors, emulsion breakers, oxygen scavengers, methanol injection and many other applications. |

Designed for use in hazardous or explosion-proof environments complying with European 'ATEX' certification. In the Oil, Refining and Petrochemical industry, Williams instruments are used for the metering of chemicals in all phases of production, processing, refining, transmission and distribution of oil and gas products. Pumps can be offered with electronic automated process control for both single or multi head dosing applications. |
The Williams 'V' pump offers simple adjustment of the stroke rate and the stroke length providing 0-100% turn down over the pump volume range. The 'V' series pneumatic chemical injection Plunger pump offers a dual seal plunger design and they offer flow rates of up to 34.75 litres an hour and operates to discharge pressures up to13,100 PsiG. An 'X' series dual seal plunger pump is also available up to the size of the CRP750-400. These units offer similar flowrates to the 'V' series, but the discharge pressures are lower. The 'X' series feature anodized aluminium oscillamatic ® controller. |

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 Body materials 316 stainless steel, diaphragm PTFEand features an intergral relief valve. The Williams WRB pumps have the option of rupture detection on the diaphragm, making the unit safer to use in environmentally sensitive areas that need to be leak free. The Wilroy series comply with european 'Atex' hazardous area certification. |
