Motor Diaphragm Pumps D

D-Series Motor-Driven Diaphragm Pumps

  • Productivity: 56 ÷ 574 l / hr.
  • Pressure: 2 ÷ 12 bar.

Motorized Diaphragm Pumps D with a mechanical drive is used to dispense liquid chemical solutions. The dosed liquid may be abrasive or contain solid impurities.

D series motorized diaphragm metering pumps capacity: 56? 574 l / h. pressure: 2 ÷ 12 bar.

Pump performance is controlled manually using a micrometer screw that controls the piston stroke length between 10% -100%. Adjustment can be carried out both on a stopped and a running pump.

Automation of performance control is possible with the use of a servo motor (optional). The servomotor independently rotates the micrometer handle of the pump and is controlled by an input signal of 4-20 mA or 0-10V DC.

It is also possible to regulate the pump performance - by changing the frequency of working cycles . This is possible when using an external frequency converter, which will change the frequency of rotation of the electric motor. At the same time, it is advisable to use pumps with special electric motors with autonomous ventilation - to prevent overheating of the engines when operating at low speeds.
