The Liverani RID Series is a range of gear box driven flexible impeller pumps. By using a gear box with twin output shafts, double headed options are available to generate either larger flow rates or higher heads. The RID MAXI DOUBLE 2Q effectively doubles the flow of the RID MAXI 80, whereas the RID MAXI DOUBLE 2H effectively doubles the head.

Within the positive displacement pump family are the flexible impeller pumps (flexible vane pumps). This type of pump is renowned for its dry self-priming ability. These pumps are therefore popular within applications which are required to have good suction lift capacity. Flexible impeller pumps are commonly used for viscous fluids, slurries and liquids containing solids and gas in low pressure applications. Thanks to their sanitary construction they are also popular as a hygienic pump.

The RID flexible vane pumps are best used for medium to high viscosity fluids or for operating at low rotational speeds for shear sensitive fluids. As the pumps are close coupled, the various inlet and outlet configurations can be better taken advantage of (a possible draw back to the GR series of flexible impeller pumps).

More information on how a flexible vane pump works and the applications it is often selected for is available here.

  • Gearbox driven flexible vane pump
  • Pulsation free pumping action for the transfer of shear sensitive liquids.
  • Solids passage capability - 10mm (MINOR) 15mm (MAJOR) 25mm (MAXI)
  • Self priming up to 6m without the requirement of a non return valve.
  • Pumps can run in both directions via a reversing switch mounted on the panel.
  • Select flexible impeller pump models are also available with 2 speed operation, controllable via a rocker switch.
  • Pump head can be rotated and installed in a range of positions.
  • Wide range of connection types available including DIN, BSP Male & Female, Triclover, SMS, RJT, Friederich, Garolla, and Macron
  • Stainless Steel AISI 304 Pipe Fittings for easy integration of the pump into existing applications are available on request to match any of the above connection types.
  • NOTE: units are supplied with Garolla connections as standard with hose fittings, clamps and seals included.
  • Pump heads are SS304 as standard. SS 316 available on request,
  • Unit can be supplied with or without a control panel
  • Dry-run protection available (50ºC is the standard set temperature however 70ºC & 90ºC options are available on request and must be pointed out at order stage). Selection of this is determined by the fluid temperature.
  • Spring loaded by-pass for the MINOR for manual adjustment of the pump capacity as well as operation with a nozzle.
  • Optional automatic drum filling kits complete with stainless steel nozzle, non return valve & pressure switch.
  • Accessories include inverter drive for variable speed operation, dry run protection, pressure switch for automatic pumping, level sensors, remote control & radio operation.
