1 model double gears fluid to 300 degrees
External Gear Pumps For Oil Transfer And Hydraulic Duty
External gear pumps for non corrosive lubricating oil and similar liquids without solids or fibre, used as transfer, booster, fuel and hydraulic pumps.
The Range
The K2CY Gear Pump
Hardened gears turn on axles inside replaceable bearing sleeves, with a safety valve built into the pump cap.
Who Buys This Line
- Oil depots and workshops transferring lubricating oil
- Engine and boiler rooms feeding fuel supply systems
- Machine builders needing hydraulic power on a skid
- Plants running lubrication circuits on large machinery
Problems It Solves
Thin oil slips past a centrifugal pump
A gear pump displaces a fixed volume per revolution, so it builds pressure on thin and thick oil alike from 5 to 1500 cSt.
Pump wear on continuous duty
Heat treated gears run in replaceable bearing sleeves, so the wearing element is a part you change rather than a pump you scrap.
Over pressure damages the system
A safety valve is built into the pump cap to protect the pump and the line if a downstream valve closes.
Why This Line
Where The K2CY Fits
Three Jobs One Pump
Transfer, booster and hydraulic duty are all inside the range, which simplifies spares across a site.
Driven By Motor Or Engine
Electric motor or diesel drive, in 380 to 415 V three phase or 220 to 240 V single phase, 50 or 60 Hz.
Connection To Suit The Skid
Flange, thread or quick coupled connections, so the pump fits an existing installation.
Application Scenarios
Typical Installations
Oil Delivery Systems
Transfer and booster duty moving lubricating oil between tanks and points of use.
Fuel Supply Systems
Delivery, pressurisation and injection duty in fuel supply installations.
Hydraulic And Lubrication Circuits
Supplying hydraulic power in a system, or feeding a lubrication circuit on plant machinery.
Industries Served By This Line
Selection Guide
Specifying A Gear Pump
Confirm The Liquid
Non corrosive lubricating oil or equivalent, free of solid particles and fibre. Abrasives destroy gear pumps quickly.
Check Viscosity Range
The pump is rated for 5 to 1500 cSt. Outside that band we will move you to another line.
Set Flow And Pressure
Flow at the working speed plus the discharge pressure the system needs, so the safety valve can be set correctly.
Pick Drive And Connection
Electric or diesel drive, flanged, threaded or quick coupled connections, horizontal installation.
Answers
Gear Pumps FAQ
What liquids suit this pump?
Non corrosive lubricating oil or an equivalent liquid without solid particles and fibre, with viscosity between 5 and 1500 cSt.
What is the temperature limit?
The data sheet gives a maximum permissible fluid temperature of 300 degrees Celsius for the pump, while the standard oil duty is quoted below 80 degrees. Tell us the working temperature so the correct build is offered.
Is there over pressure protection?
Yes, a safety valve is built into the pump cap.
Can it be driven by a diesel engine?
Yes, electric motor and diesel drive are both listed for this pump.
Which materials are available?
Casing and inner parts in cast iron, stainless steel or bronze, with a shaft seal ring at the axle end.

Selecting A Pump For A Thermal Oil Or Hot Water Circuit
Above 80 degrees the usual assumptions stop working. Seal choice, expansion, venting and material all move at once, and the pump is only part of the answer.
