Construction

The GC range are vertical In-line centrifugal pumps, close coupled to an electric motor. The top-pull-out construction allows access to the impeller and mechanical seal without disturbing the suction and discharge pipework. Suction and discharge flanges are arranged on a common centreline for easy installation into a pipeline. The single stage closed impeller, with double curvature vanes for optimum efficiency and good suction performance, is statically and dynamically balanced for vibration free operation.

Electric motors

Apex GC pumps are supplied with a TEFC IP55 electric motor. Alternative motors including Eexd flameproof motors are readily available.

Materials

The pump pressure containing parts are cast in a variety of materials, selected  to suit the working pressure of the pump, and to be compatible with the liquid being handled. Available materials are:

  • Cast iron
  • Ductile iron
  • Cast 316 Stainless steel
  • Cast bronze
  • Cast steel
  • Specialist steels eg Duplex, Hastalloy, Titanium

Flanges

Standard flanges are drilled to the British Standard BS4504, with pressure rating to suit the specific application:

  • BS4504 PN16 | 16 bar working pressure
  • BS4504 PN25 | 25 bar working pressure
  • BS4504 PN40 | 40 bar working pressure

ANSI standard flanges drilled to 150 lb or 300 lb ratings and all other standards are available on request.

Seals

The standard arrangement is a single mechanical seal. Double seals, balanced seals, cartridge seals and packed gland seals can be fitted to suit the application and to meet customers’ preferences.
