Vane/ Screw Pump

With decades of experience in the design and manufacture of rotary positive displacement pumps, Plenty Mirrlees Pumps has built

an excellent reputation supplying reliable pumping equipment to the oil processing, petrochemical processing, power generation,

marine, defense, sugar and general industries.

Plenty Mirrlees Pumps has a solution for most pumping applications with a range that includes  our Vane Pumps with unique 2000

series rotary pumps and TRIRO – Triple Screw Pumps:

  • VANE PUMPS

  • U2000 ROTARY PUMPS

  • G2000 FIXED FLOW ROTARY PUMP

  • P2000 FIXED FLOW (BELT DRIVEN) ROTARY PUMP)

  • TRIRO – TRIPLE SCRREW PUMPS

 

U2000 ROTARY PUMPS

The U2000 rotary pump is specifically designed for systems or processes where infinitely variable flow from 0-100% of the rated pumps capacity is required. The U2000 achieves this with a variety of Control Types,without the need for speed variation devices, bypass lines/loops or control valves

Operating Parameters

Capacity 0 to 265 M3/hr 2200 USGPM
Pressure up to 14 (Standard)

Viscosity 2 to 75,000 cst

Temperature -30 to +260 C

Applications

  • Almost any process plant variable flow requirement
  • Typically: Lube oil blending, bitumen blending, ships bunkering

 

G2000 FIXED FLOW ROTARY PUMP

The G2000 is a fixed flow, heavy duty, transfer pump.  It is available in a variety of materials to suit various fluid types.

Capacity  265 M3/hr 2200 USGPM
Pressure  14 Bar (Standard)

Viscosity 2 to 75,000 cst

Temperature -30 to +260 C

Typical Liquids

  • Oils
  • Grease
  • Bitumens
  • Polymers
  • Molasses
  • and other viscous liquids

 

P2000 FIXED FLOW (BELT DRIVEN) ROTARY PUMP

The P2000 rotary pump is specifically designed for space constrained installations, or where a simpler belt-driven design is preferred.  The P2000 rotary pump is available in two different designs :

Inboard roller bearing configuration with single mechanical sealing for duties involving lubricating liquids, such as Fuel Oils, Vegetable Oils, Lube Oils, and Additives.

Inboard plain bearing configuration with gland packing for duties involving non-lubricating liquids, such as Molasses, Resins, and Polymers.

Operating Parameters

Capacity up to 50 M3/hr 220USGPM
Pressure up to 12 Bar 175 Psi
Viscosity up to 75,000 cSt 350,000 ssu
Temperature up to +120 C +250° F

TRIRO – TRIPLE SCREW PUMPS

The Triro pump is of the positive displacement axial flow screw type with only three moving parts – a power rotor and two idler rotors.  These three rotors (hence the brand name TRIRO) have accurately machined intermeshing threads which enfold the liquid being pumped and act as seals in relation to each other and to the pump body or sleeve in which they rotate.
