DJ Pump Engine Cooling Pumps and Impellers
For over 30 years DJ Pump has been manufacturing and supplying the marine industry with quality marine pumps and accessories. DJ Pump Impellers are manufactured in their hi-tech Korean ISO certified facility to exacting standards ensuring consistent quality and reliability the range of DJ Pump impellers are subjected to quality testing to ensure reliability and continued performance.
Flexible impeller pumps are used extensively in the marine industry and are designed to provide an efficient method of pumping raw water to a large number of applications where required. Often an integral part of the engines cooling system, these pumps operate using an internal impeller which is designed to circulate water continuously throughout the engine.
To satisfy the replacement market DJ Pump manufacturers a wide range of popular impeller vane and shaft configurations in Neoprene for general fresh and seawater applications and to a lesser extent in nitrile for oil and diesel applications.
DJ Pump impellers can be fitted to most makes and models of flexible impeller marine engine cooling, bilge, electronic clutch and multi-purpose pumps and are manufactured from quality materials to provide excellent longevity without sacrificing flow characteristics.
Available in a wide range of shaft, diameter and depth configurations each impeller is packed in an easy to identify box clearly showing shaft, material and brand replacement codes.
The impeller is a very important security device. Its task is to pump the water through the cooling system of the engine. But remember that the impeller should be replaced every year. Remove the impeller with a slip joint plier or an Impuller.

DJ Pump Impeller Reference guide
DJ Pump Impeller 08-21-1201 suits the following models:
Use Neoprene Impellers for engine cooling, and for fresh or salt water transfer duties. Neoprene is the most commonly used material and is suitable for use where only small amounts of oil or diesel fuel are present.
Use Nitrile Impellers for bilge pumping, and for transfer duties where the water is heavily contaminated, for example by oil or diesel. Replace all impellers at least once every year, or sooner, depending on the engine duty. When the installation is correct an impeller may last for several years, but it is always advisable to stick to a schedule of preventative, rather than corrective maintenance. By removing the end cover screws, it is possible to remove the impeller by using either a Impeller Removal Tool, or channel lock pliers, to grip the hub of the impeller. Don’t use screwdrivers as they may damage the face of the pump body, causing leaks, and they can be dangerous in confined spaces. Always carry spare impellers on board in case of emergency. The impeller is one of the most vital components of the engine cooling system and should always be treated as such. Always grease new impellers.
Firstly, it makes it easier to install the impeller into the pump bore, and secondly it gives added protection to the impeller during initial prime.
After replacing the gasket and end cover the pump is ready to use.
