Positive Displacement Industrial Pumps

Precise, high-pressure, and viscous fluid handling for demanding processes.
Positive Displacement (PD) pumps move fluid by trapping a fixed volume and mechanically forcing it into the discharge pipe, making them ideal for applications requiring accurate metering, high pressure, or handling of thick, viscous, or shear-sensitive fluids. EKG Malaysia supplies, installs, and maintains a full range of PD pumps for chemical, food, pharmaceutical, oil & gas, and manufacturing industries.

Key PD Pump Types We Provide:

• Rotary Pumps:

  • Gear Pumps (Internal/External): For moderate viscosity fluids, lubricating oils, and fuel transfer.

  • Lobe Pumps: Gentle handling for food, pharmaceuticals, and slurries. Can handle solids.

  • Progressive Cavity (PC) Pumps: For very high viscosity, abrasive slurries, and shear-sensitive materials (e.g., sludge, paste, chocolate).

  • Peristaltic (Hose) Pumps: For abrasive slurries and sterile applications; fluid contacts only the tube.

  • Vane Pumps: For hydraulic oils, LPG, and solvents.

• Reciprocating Pumps:

  • Piston/Plunger Pumps: For extremely high pressures (hundreds of bar) in water jetting, boiler feed, and oilfield services.

  • Diaphragm Pumps (Air-Operated & Electric): For hazardous, abrasive, or viscous fluids; leak-free by design.

Characteristics & Advantages of PD Pumps:

• Constant Flow: Delivers a nearly constant flow rate regardless of discharge pressure (with variable speed control).

• High Pressure Capability: Especially reciprocating designs.

• Handles High Viscosity: Maintains efficiency with thick fluids where centrifugal pumps struggle.

• Self-Priming & Good Suction Lift: Can handle suction conditions difficult for centrifugal pumps.

• Accurate Metering: Capable of precise volumetric dosing.

Critical Industrial Applications:

• Chemical Processing: Metering additives, transferring polymers, dosing catalysts.

• Food & Beverage: Pumping syrup, dough, fruit concentrates, and fillers.

• Wastewater & Sludge: Transferring thickened sludge and dosing treatment chemicals.

• Oil & Gas: Chemical injection, glycol transfer, mud pumping.

• Manufacturing: Adhesive application, lubricant transfer, paint circulation.

Our PD Pump Services:

1. Application Engineering: Matching pump type to fluid properties (viscosity, abrasiveness, temperature) and process requirements (flow, pressure, accuracy).

2. System Design: Designing pulsation dampeners, pressure relief valves, and suction stabilization systems critical for smooth PD pump operation.

3. Supply & Installation: Providing the pump, drive, controls, and ancillaries as a complete package.

4. Commissioning & Training: Setting flow rates, relief valves, and training operators on proper use.

5. Maintenance & Parts: Supplying wear parts (stators, diaphragms, seals) and providing overhaul services.

When flow must be precise, pressure high, or fluid tough.
Positive displacement technology solves the pumping challenges that centrifugal pumps cannot.
