Oil Pumps – Heart beat of the engine (Part 3)

Pump drive

Mechanical oil pumps are the simplest solution to ensure continuous flow rates and maintain engine lubrication. Generally driven by the crankshaft, pumps can be driven by the camshaft or balance shaft to reduce pump speed. Oil pumps are gear driven from crank or camshaft but can occasionally be driven by an external belt or chain.

Key Description Notes Image
ADP Auxiliary Driven Pump Driven by an auxiliary source such as a Balance Shaft, this is a compact design most commonly used in VW/Audi/Seat/Skoda. Their popularity seems to have increased recently due to their compact nature, and simplistic design. Meaning they can be fitted into awkward locations, unlike Belt and Chain driven pumps.  
BDP Belt Driven Pump Equipped with a Pulley rather than a Sprocket, this design is driven by a Rubber Belt, much like a Water or Vacuum Pump. Currently we only have 1 type of this pump in our programme, however applications such as the Ford Eco boost are now utilizing Dry and Wet Belt designs - So we may very well see this become more popular in the future.  
CDP Chain Driven Pump With more modern vehicles being equipped with Timing Chains, the Oil Pump has followed this trend by being driven by a Chain system. In a lot of cases we offer an OPCK (Oil Pump Chain Kit) which we recommend to be replaced when changing the Oil Pump or Timing Chain Kit. The Chain Driven design is now a large staple of our range, being fitted to some of the most popular applications such as Ford, Citroen and Peugeot Light Commercial Vehicles.  
CSDP Crankshaft Driven Pump Situated directly on the end of the Crankshaft, this design usually incorporates a cover which sits directly above the Sump. Most commonly this design of pump can be found on Vauxhall/Opel, Fiat, Alfa Romeo. With the most popular version in our range OP308/OP338/OP341 for the 1.3 Multijet engine.  
GDP Gear Driven Pump Gear driven pumps include an intermeshing gear, which are predominantly used on Heavy Duty Diesel applications where the capacity is around 2.5 liters or more. In most cases they can be found on Mitsubishi, Ford and Mazda Pickup or Light Commercial Vehicle applications.  
SDP Shaft Driven Pump Incorporating a drive shaft, this type of pump is usually driven off a Camshaft or Intermediary Shaft. These usually have a Spline or Slot fitment on the end of the shaft. In most cases these are fitted to earlier VW/Audi/Seat/Skoda applications.
