Diaphragm motor pumps ST-D

ST-D Series Motor-Driven Diaphragm Pumps

  • Productivity: 10 ÷ 148 l / hr.
  • Pressure: 5 ÷ 14 bar.

ST-D diaphragm motor pumps with a mechanical drive is used to dispense liquid chemical solutions. The dosed liquid may be abrasive or contain solid impurities. The pump is able to provide productivity: 10? 148 l / h. pressure: 5 ÷ 14 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.

On request, models with a servo motor are delivered, which independently rotates the micrometer handle of the pump and is controlled by an input signal of 4-20 mA or 0-10V DC.

Specifications:

  • ST-D series diaphragm chemical metering pumps in a compact mini design.
  • AA Configuration — pump head — n / a AISI 316l, membrane — PTFE (Teflon);
    CA — pump head — PP, membrane — PTFE (Teflon).
  • Productivity: 10 ÷ 148 l / h, pressure: 5 ÷ 14 bar;
  • Pumps are CE compliant;
  • The pump casing is made of cast aluminum, protected by epoxy, anti-acid paint;
  • Protection class: IP55, degree of isolation: F-S1 - IEC 34-1;
  • Pump performance is controlled by a micrometer knob that controls the stroke length of the piston;
  • The metering pump is driven by a vertically mounted motor;
  • The gearbox operates on the principle of idling (the piston is returned using the return spring);
  • Standard motor: 0.18 kW, 230 / 400V, 3 phases, 50 Hz .;
  • Other types of engines are made to order.
