Materials

For pump with horizontal base plate

  • Impellers made of stainless steel AISI 316/ 1.4401
  • Pump housing made of grey cast iron EN-GJL-250
  • Shaft made of stainless steel AISI 431/ 1.4057

Description/construction

  • Base frame: Manufactured from profiles consisting of electro-galvanised steel with brackets for the switch cabinets and the outlet manifold. Special square holes at the bottom for forklift trucks, as well as integrated hooks for lifting slings. Side profiles at the top on each side to enhance the rigidity of the system when moving and lifting.
  • Plastic cover at the rear which provides visual access to the valve position and pressure gauge.
  • Pipework: Complete pipework with flanges made of epoxy resin painted steel, suitable for the connection of all common piping materials; the dimensions of the pipework must correspond to the overall hydraulic performance of the pressure boosting system
  • Pumps: 1 or 2 pumps with horizontal base frame - EN 733 - with spacer coupling, electric or diesel motor.
  • • Back-pull-out model to ensure the internal parts of the pump are easy to access without having to move the motor or piping.
  • Valves: The main pumps are fitted with a shut-off valve and non-return valve on the discharge side, both of which are painted with epoxy resin and adapted for a flange connection.
  • Diaphragm pressure vessel: Diaphragm pressure vessel 20 l/PN16, on the discharge side of the jockey pump, with drain plug.
  • Tank: The fuel tank is made of metal painted with epoxy resin and is located behind the bracket of the switch cabinet
  • Sensors and display: 2 pressure switches, 2/16 bar per pump, on the discharge side, for activating the pump start via the SCFire controller and regulator. The discharge side pressure gauge (∅ 63 mm) is located in the middle of the rear panel.
  • Controller: The system is equipped as standard with a separate switchgear/control device (SC Fire) for the electric or diesel motor and a switchgear/control device for the jockey pump.
