Series P Non-Metallic Pumps

Granzow Non-Metallic Series P Diaphragm Pumps
Solid and Injection-Molded PP, PTFE & PVDF Air-Operated Diaphragm Pumps

Non-metallic pumps are used in galvanic, coating, paint, varnish, pharmaceutical, chemical, waste water and building industries, and are made of mechanically manufactured or uniquely designed injection-molded plastic parts. Non-metallic pumps were designed for problem-free pumping of corrosive and abrasive products in such applications.

  • 1/2"-3"Pipe Sizes
  • 5-100 psi Air Pressure
  • PP, PM, PL, PT, TL Pump Types
Features & Benefits

Technically, usable metals do not always possess the required chemical resistance when being used with corrosive media. Series P non-metallic pumps were subsequently developed, as the individual parts are made of plastic material. When developing the non-metallic pumps, the objective was to not introduce any pumping pressure reduction in contrast to the cast metal pumps. These pumps can also be used up to a maximum pressure of approximately 100 psig.

Despite the compact construction, Series P non-metallic pumps offer a high level of mechanical stability. Pumps constructed of electrically conductive plastic materials further enhance the product range. These enable the conveyance of non-conductive products in explosion-endangered environments. Depending on the application, there are five types of electrically conductive polypropylene or PTFE models available.

The wide range of construction materials enables the universal use of these non-metallic pumps. A choice can be made between internally or externally mounted air control valves. ANSI, DIN and JIS flanges, as well as threaded connections, are alternatively available. Product contact parts (diaphragms, valve seats and balls) are available in a selection of materials to ensure compatibility with a wide range of pumped media.

Double-acting, positive displacement Series P pumps operate with two alternating pumping chambers. The compressed air which drives the unit is admitted through a control valve, to the rear of each diaphragm in turn, so displacing the medium from alternate pumping chambers. Since the two diaphragms are connected by a common piston rod, suction always occurs in one chamber while discharge occurs in the other.
