Descriptions of PLAST-O-MATIC VPA

  • Plast-O-Matic chemical metering pumps are designed with 4 chambers: a liquid chamber, a vented chamber, and two air operating chambers.
  • Movement within the chambers is controlled by the reciprocating action of the pump’s shaft and piston assembly. The assembly is operated and controlled by a 4-way air valve (an accessory item listed on page 4) which alternately introduces and exhausts air pressure on both sides of the air piston.
  • The 4-way valve would receive its on-off electrical signal from an independent electrical timer or similar device, not supplied with the pump.
  • This action also causes the liquid piston to reciprocate.
  • On the down stroke of the liquid piston a vacuum is created in the liquid chamber which opens the inlet check valve diaphragm and holds the outlet check diaphragm closed. This operation permits the liquid chamber to fill itself (self-priming).
  • On the up stroke the liquid in the chamber is pressurized by the piston movement
  • This opens the outlet check valve diaphragm and holds the inlet check valve diaphragm closed. This action discharges the liquid out of the pump.
  • All Plast-O-Matic chemical metering pumps are positive displacement pumps thus any re-adjustments to the adjusting bolts will result in a change in discharge quantity. By turning the bolt further into the lower air chamber the travel of the shaft and piston assembly is restricted creating a shorter discharge stroke and reducing discharge quantity.
