Motor Driven Diaphragm Metering Pumps

  • Maximum Flow Rate: 200 L/h
  • Maximum Pressure: 15 kg/cm²g
  • Mechanically Actuated Diaphragm

Performance Capacity

Flow rate up to 200 l/h & pressure up to 15 kg/cm²g. For reliable dosing with high flow capacity and consistent pressure handling.

Durable Diaphragm

PTFE Hypalon diaphragm for long service life. Ensures excellent chemical resistance and durability, reducing maintenance.

Advanced Mechanism

Mechanically actuated diaphragm with stable operation. Features a slider-polar crank system that minimizes pulsation.

Flexible Flow Control

Adjustable flow rate from 0–100% during operation. Allows precise control with ±2% accuracy (from 10%–100% stroke).

Operational Efficiency

Supports suction lift up to 1.5 m, handles liquids up to 100 cps viscosity, and offers a turn-down ratio of 10:1.

Robust Build & Design

Simplex configuration with oil bath lubrication. Efficient lubrication for long-term reliability and can handle liquid temperatures up to 50°C.
