Description

The hydraulic double diaphragm metering pump is a high safety pump for precise metering and transportation of special media. Based on hydraulic diaphragm pump design, it adds double diaphragms and a monitoring system, effectively avoiding the rupture risks of single diaphragm pumps.

hydraulic diaphragm metering pump Technical Parameters:

  • Single-head flow: Qmax = 1600 L/H
  • Pressure range: Pmax = 70 MPa
  • Standard configuration: material 304, 316, 380Vac, 50Hz
  • Optional configuration: material 316L, PVDF, 904, 2205, TA, Hastelloy C, etc.; motor frequency conversion, explosion-proof, special voltage, frequency

hydraulic diaphragm metering pump Main features:

  1. Double diaphragm design: Hydraulic end uses double diaphragm sealing for no leakage and higher safety. Vacuum fit during operation ensures high precision metering.
  2. Broken diaphragm monitoring system: Built-in sensor detects rupture within 0.2 seconds, triggers alarm and stops the pump, with signal feedback to the control room for timely maintenance.
  3. Excellent diaphragm material: PTFE diaphragm provides corrosion and temperature resistance for harsh environments.
  4. Automatic pressure relief protection: Overload valve enables automatic relief to prevent overload (not for long-term use).
  5. Wide applicability: Suitable for high/low temperature, high viscosity, corrosive, flammable, explosive, toxic, malodorous, radioactive, and other special media. Supports dual/multi-head parallel configuration for increased flow, reduced pulse, or simultaneous multi-media delivery.
  6. Automation control: Optional stroke controller for more accurate automation.

hydraulic diaphragm metering pump Advantages:

  1. Fast control system response, high safety, superior to traditional display meters.
  2. Adjustable eccentric mechanism, 0-100% stepless stroke adjustment, high metering accuracy and stability, error control within ±1%.
  3. Metal diaphragm (single or multi-layer) withstands up to 70MPa pressure.
  4. High-precision check valve assembly (ball, stack, angle type), valve seat usable on both sides for reduced maintenance costs.
