Talk to Our Positive Displacement Experts

If your business depends on precision and reliability, Tapflo UK’s Positive Displacement Pumps, including both reciprocating and rotary models, are designed to keep your operations running smoothly. Engineered to handle high-viscosity, abrasive, or shear-sensitive fluids, these pumps maintain a constant flow, even under fluctuating pressure conditions. 

With features like ATEX-rated models for explosive environments and options for hygienic applications, our Positive Displacement Pumps offer unmatched versatility. They are built to last, reduce maintenance, and handle complex fluid types with ease, ensuring consistent performance across every batch or production run. 

 

Reciprocating vs Rotary: Which to Choose:

Reciprocating Positive Displacement Pumps: 

Reciprocating Pumps work by moving a diaphragm, piston, or plunger in a back-and-forth (reciprocating) motion to create suction and discharge. Common types include Diaphragm, peristaltic, and Flexible Impeller Pumps. They are highly effective for: 

  • Applications requiring high pressure 
  • Handling corrosive or abrasive materials 
  • Low-flow applications where controlled flow is essential  

Applications: 

  • Chemical processing 
  • Water treatment 
  • Pharmaceuticals 
  • Food & Beverage (CIP systems) 

Rotary Positive Displacement Pumps: 

Rotary Pumps use a rotating mechanism (gears, lobes, or screws) to move fluid. Common types include Gear, Lobe, Screw, and Vane Pumps. These pumps are perfect for applications that require: 

  • Smooth, continuous flow 
  • Handling viscous fluids like oils, creams, and syrups 
  • Suction Lift Applications where fluids that need to be lifted from tanks or containers 

Applications: 

  • Food & Beverage (high-viscosity fluids like syrup, chocolate, oils) 
  • Pharmaceuticals 
  • Cosmetics 
  • Oil & Gas 

Benefits of Using a Positive Displacement Pump:

  • Accurate flow control at high differential pressures  
  • Self-priming and dry-run capabilities for easy operation 
  • Handles viscous and abrasive fluids with minimal wear to the pump components 
  • Air-driven and electrically driven options for operational flexibility 
  • Explosion-proof models for use in hazardous environments
