Advantages of Teikoku metering pumps

  • Best class suitability for handling toxic, flammable & dangerous fluids, odorous fluids, solidifying fluids, deteriorating fluids in exposure to atmosphere
  • Solid suspension fluid and high viscosity fluid can be handled.
  • Its state-of-art stroke length adjustment enables high precision metering in very wide range of flowrate, with reciprocating accuracy < ±1, repeatability < ±3%, linearity <±3%.
  • The most durable check valves shall be outfitted to be the best suited for given conditions.
  • Diaphragm rupture detector is a standard outfit of PTFE diaphragm pump.
  • Reengineered stroke length adjustment, combination & replenishing valve, etc., has accomplished the diminished number of constituent parts and the enhanced maintainability.
  • Its unique sealing design and the production know-hows has accomplished very reliable safety feature and reliability.
  • Pneumatic actuator to remotely perform flow control can be installed as an option.
  • If some leakage to the outside is acceptable, plunger pump can be selected.
  • Wide range with discharge pressures up to 500 barg and flow rates up to 4000 L/h 

Teikoku metering pump types

All types are available with either ball, disc, or special check valves, tailored for the application.

Metering pump accessories

Safety valve / Relief valve
Install in pump discharge line for protection of the piping.

Back pressure valve
Install in the discharge line when differential pressure between suction and discharge is small.

Diaphragm rupture detector pressure switch/transmitter
Pressure switch/transmitter can be mounted for remote monitoring of diaphragm rupture.
Calibration pot
Install calibration pot to check the actual discharge flow.

Pulsation damper
Diaphragm type, Air chamber type, Bladder type, or Metal bellows type. Install in pump suction line when pressure-loss by hydraulic pulsation needs to be reduced. Install it in discharge line when pulsation is required to be surpressed.
