Positive Displacement Pumps

Positive displacement pumps are essential for delivering a consistent flow of fluids, regardless of pressure changes, making them ideal for precision-driven applications across various UK industries. These pumps are widely used for their ability to handle viscous, abrasive, and sensitive fluids with accuracy. Their robust design and steady performance make them suitable for everything from food processing to chemical transfer. They offer accurate, reliable flow control, especially in systems requiring steady pressure or handling thick and shear-sensitive materials.

Dosage pumps with high chemical resistance Blackstone pumps are designed for industrial use. Easy to install, with wide, flat bases and mounting holes to allow for tank, shelf or floor mounting (horizontal mounting). Mounting holes are also available on the rear of the pump. The external flow control (the potentiometer) on the front of the pump allows for adjustment of flow from 0 to 100% of the nominal capacity of the pump. An LED indicator lights up on every pulse. These pumps are manufactured to the highest degree of mechanical precision, with materials selected for their intrinsic abilities to withstand chemical attacks. The diaphragm is made from PTFE which, unlike regular laminated diaphragms, is wear resistant. The balls are made from glass. The pump heads and o-rings are made from Kynar®, PTFE or Viton®. Blackstone pumps are fitted in such a way as to be completely hermetically sealed, with protection against splashing and accidental spillages. The reinforced polypropylene housing withstands chemical attacks and offers superior strength, suited to challenging industrial environments. Self-priming: max. height 1.5 m Max. power: 200 W Adjustment button: 0 → 100 % Metering/Dosing Pumps For use in the chemical, pharmaceutical and food/drinks industries. All have IP65 glass fibre reinforced housings, solenoid drive mechanisms and LCD displays. A comprehensive user manual is supplied with each model.
