The Twinro 2 screw pump is a heavy duty, fixed flow transfer unit.  It is available in either Iron, Steel or Stainless Steel constructions to suit a variety of duties.  The design of the screwset means the screws intermesh without metalic contact, making the pump suitable for non-lubricating duties.  The pump is available in two configurations:

• Outboard bearing pumps suitable for non-lubricating liquids, such as Petroleum Liquids, Palm Oils, Fatty Acids and Water Emulsions.

• Inboard bearing pumps suitable for lubricating liquids, such as Lube Oils, and clean Fuel Oils.

• API 676 and other specifications
  Plenty Twinro pumps can be supplied in accordance with the requirements of API 676.  Other international pump standards or clients specifications can be accomodated.

• Unitisation
  Plenty Twinro pumps can be supplied bareshaft or fully assembled with driver on a baseplate with coupling and guard.

• Pump Sealing
  Plenty Twinro pumps can be supplied with single or double component or cartridge style seals.

• Relief Valve
  The Twinro range has a built-in full flow relief valve for pump protection, as standard.

• Relief Valve Jacking Device
  The Twinro range can be fitted with a relief valve jacking device to manually lift the relief valve from its seat. This device allows for recirculation of the liquid to aid extreme suction or discharge conditions.  The RVJD is useful during cold start conditions to avoid the need to oversize the driver.

• Dry Running
  The Twinro range can be fitted with a dry running facility to allow full loading and unloading cycles.

  The Twinro range has good self-priming capabilities to evacuate air from suction lines.
