BW Mud Pump

A Mud pump refers to a machine that transports flushing fluid such as mud or water into the borehole during drilling. Besides, it’s an important part of drilling equipment.

What is a Mud Pump used for?

BW drilling mud pumps are used to pump the medium containing solid particles. According to the process conditions, the equipment should be suitable for handling abrasive or corrosive liquids.

In the common positive circulation drilling, a mud pump provides pressure to the surface flushing medium, such as clean water, mud, or polymer flushing fluid. Under this pressure, the surface flushing medium will go through the high-pressure hose, faucet, and the center hole of the drill pipe string, directly to the bottom of the drill bit. Then it can achieve the purpose of cooling the drill bit, removing the cutting debris, and transporting debris to the surface.

This is BW series triplex mud pump, a kind of horizontal type, 3-cylinder, single-acting reciprocating piston pump. The followings are about the parameters of different types.

YG Machinery offers a series of special high-pressure pumps for circulating drilling mud through a drill pipe that is specifically designed to handle mild and heavy mud. The BW series mud pump of YG Machinery is piston type. The crankshaft of the pump is driven by the power machine to rotate, and the crankshaft drives the piston to reciprocate in the pump cylinder through the crosshead. Under the alternate action of suction and discharge valves, the purpose of pressure feeding and flushing liquid circulating is realized.

Types of Mud Pumps

Commonly, mud pumps can be divided into:

  1. The pump seal type can be divided into piston or plunger type
  2. From power type, can be divided into the electric type and diesel type
  3. From a number of cylinders of the pump, there are single-cylinder, double-cylinder, three-cylinder, five-cylinder, and other types.

The Usage

  1. Grouting reinforcement, anchoring grouting.
  2. Pump thin mud, sewage, and mixed water.
  3. Transport cleaning fluid for drilling rig.

Wearing Parts of Mud Pump

As is known, the vulnerable parts are mainly the pump casing, bearing, impeller, etc.

BW series mud pumps adopt advanced anti-wear measures to increase the service life of vulnerable parts, reduce engineering investment and improve production efficiency. At the same time, Henan Yugong Machinery will provide replacement parts for clients. These wearing parts should be kept ready for timely replacement.
