Bearings for Oilfield Drilling Equipments, Mud Pump Bearings

Mud pumps, used for oil and gas drilling operations, get their name from the specially prepared fluid (mud) that is pumped through the drill pipe to evacuate cuttings from the hole, as well as to cool and lubricate the drill bit. 

These are generally low speed, high displacement reciprocating pumps and can be either single- or double-acting, with the majority in use today being singleacting. Mud pumps can also feature from one to five cylinders, with a triplex arrangement being the most common. Normally, the pumps are skid mounted for transportation purposes, with the majority being horizontal in design and incorporating a fluid and power end, which are separate for maintenance purposes.
