The YK series of Internal Eccentric Gear Pump are designed for the pumping of low to high viscosity fluids with lubricating properties. Available with and without an external bypass relief valve, these gear pumps are also available with an external heating jacket to prolong the temperature of the medium being pumped. The clearance between the gears is tight and therefore means that these eccentric gear pumps are unable to pump fluids containing abrasive particles. Common uses for these internal gear pumps include fuel oil transfer, diesel fuel transfer, coolant transfer, OEM, hot oil circulation, food industry, marine, detergent industry and lubrication.
Features of the Yildiz YK gear pump:
- Internal eccentric gear pump
- Compact design
- Reliable construction thanks to only two moving parts
- Various material options
- Available with external bypass, jacketed and blind cover
- 230v, three phase 50/60hz motors available
- Motor and gearbox drive available

Bitumen Emulsion for Electrical Engineering Company - Gear Pump
Castle Pumps pride themselves on providing perfect solutions to every customer’s requirements and this case study is a prime example. In addition to a quick turnaround, the customer needed a precise operating temperature, capacity and discharge pressure, and the fluid needed to maintain the same temperature whilst being pumped. Thanks to our extensive knowledge and experience, we provided the customer with a pump that matched their requirements just 32 days from their initial enquiry.
Lube Oil Transfer for Tanker Loading Specialist - Gear Pumps
This customer required a gear pump for their 4 custom skids that they were building. Each pump was required to transfer 30m³/hr at 4 bar and to have a built in bypass. Each pump was coupled to an 11Kw geared motor running at 400RPM to achieve the required duty. We also supplied detailed drawings of the pump, to allow the customer to begin manufacturing the skid before the pumps were delivered.
Diesel Transfer System for Generator Manufacturer - Gear Pumps
This generator manufacturer customer needed a pump set for transferring fuel in bulk with a lift height of 26.5 meters and total pipe length of 80 meters. We were able to select 2 of our gear pumps which were ideal for the requirements this customer was after.
Viscous Resin Transfer in Polymer Production Line - Gear Pump
Castle Pumps investigate all aspects of a customers requirements when specifying a pump, as it's essential to select the right pump for their needs. This case study shows that the customers requirements required further investigation in order for us to decide which pump would be best suitable for their requirements.
FAQs
Gear pumps operate by an unchanging volume of fluid passing between the teeth of two meshing gears and their casing at a constant rate (not between the gears themselves). As the gears rotate and the meshed teeth separate, a partial vacuum is formed that fills with fluid, which they trap and move it around the casing from the suction to the discharge point.
The pumping of high viscosity lubricating fluids such as oils, fuels, paints, soaps and resins. The pumping of low viscosity fluids should be avoided as they can cause fluid to leak backwards or "slip" back to the suction side.
An internal gear pump operates a "gear within a gear" principle, whereby one gear (the idler) is positioned inside another gear (the rotor).
Whilst external gear pumps offer higher pressure and flow rates, internal gear pumps generally have better suction capabilities and are able to handle higher temperature, higher viscosity fluids. Internal gear pumps slower speeds and larger clearances also makes them more suitable for shear sensitive fluids
Yes. Gear pumps have excellent self-priming capabilities thanks to their rotating gears evacuating any air in the suction line, and forcing the liquid into the pump inlet.
The close tolerances between the gears and casing mean that pumping solids will result in wear and damage. Some internal gear pump designs which have less tight tolerances and slower speeds however may be able to tolerate small solids.
