Williams 'V' Series Pneumatic Plunger Pumps, Pump Performance. *

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.

'Wilroy' Series Pneumatic Diaphragm Pumps, Pump Performance.*

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.
