This is a air-driven hydraulic booster injection device, equipped with a flow regulating valve and a buffer accumulator tank, which can adjust the flow rate with high precision and effectively reduce the pulse value of the flow meter pointer.

The equipment adopts pure mechanical elliptical gear flowmeter for petroleum industry, which is mainly used in petroleum, chemical and other industries. Its characteristics are high precision, pure mechanical metering, and no explosion-proof requirements.


Portable Hydrostatic Pressure Pump With Oval Gear Meter
  • ●  Low-pressure compressed air as the booster power source, safe and environmentally friendly.
  • ●  Equipped with 2 pumps, one for use and the other for standby, which can prevent the operation from being stopped due to the failure of only one pump;
  • ●  Infinitely variable output pressure and flow.
  • ●  Holds static pressure without generating heat or consuming power.
  • ●  Pressure self-locking function, under the condition of setting the driving air pressure, the output pressure is constant.
  • ●  Dual scale shockproof pressure gauge display.
  • ●  Equipped with a metering valve that can adjust the output pressure slightly and accurately control the output pressure.
  • ●  No heat, flame or risk of spark.
  • ●  Well proven and trouble-free operation.
  • ●  Designed for ease of maintenance.
  • ●  Low cost servicing.
  • ●  Compact, robust, self-contained structure.
