Wholesale of gear oil pump

How to improve the service life of cast iron gear pump? Cast iron gear pumps are mainly suitable for situations with lubricity, viscosity below 1500cst, medium without solid particles, and temperature below 80 ℃. In a high-quality working environment like this, the service life of a conventional gear pump is relatively long, usually 3-5 years. As time goes by, the pressure of the gear pump will become lower and the flow rate will become smaller, and there will be leakage in the seal. In severe cases, it may not be able to pump oil. This situation is basically a normal wear and tear of the gear pump. Especially when transporting lubricating grease media, some media may not be very clean, and some may contain small particles such as residual oil, reused heavy or light fuels used in boiler combustion. If you want to improve the service life of gear pumps on the basis of conventional gear pumps, you must start from the following points:; (1) Replace the gear material of the gear pump, adjust it from the conventional 45 grade material to 40Cr material, and perform quenching and tempering treatment. (2) The thrust plate of the gear pump has been changed from cast iron material to cast steel material. (3) The shaft sleeve has been changed from the original steel backed composite sleeve to a stainless steel shaft sleeve or a silicon carbide shaft sleeve.
