Motor Driven Diaphragm Metering Pumps

  • Maximum Flow Rate: 100 L/h 
  • Maximum Pressure: 15 kg/cm²g 
  • Mechanically Actuated Diaphragm

Key Specifications

Flow (LPH)

0 - 100

LPH

Flow rate up to 100 l/h with pressures up to 15 kg/cm²g.

For reliable dosing applications, offering precise performance with a 10:1 turn-down ratio and flow adjustment from 0–100% while running.

PTFE Hypalon diaphragm for enhanced durability.

The mechanically actuated diaphragm design provides dependable operation and extended service life in demanding environments.

Smooth & Stable Operation

Variable eccentric stroke adjustment minimizes pulsation and shock. Smoother fluid delivery, improved process stability, and reduced mechanical stress.

High metering precision across the operating range.

Delivers ±1% accuracy of rated flow from 10% to 100% stroke, supporting consistent and reliable dosing performance.

Handles a wide range of operating conditions.

Suitable for liquids up to 50°C, viscosities up to 100 cps, and provides suction lift capability of up to 1.5 m water.

Simplex configuration with oil-bath lubrication.

Combines a straightforward single-head design with efficient lubrication for long-lasting, low-maintenance operation.
