Product Description

Description:

BW-250 mud pump is a horizontal triplex single-acting piston pump. For this drilling pump. two cylinder diameters and four shifts of speed are available. Triplex mud pump with large cylinder diameter (Φ80mm) is applicable for large-diameter drilling machine, while pump with small cylinder diameter (Φ65mm) is suitable for small-diameter drilling machine. Both of the mud pumps enjoy four shifts of displacement and suite well for different hole depths and diameters. This drilling pump is also perfect for cement mortar grouting with the water cement ratio reaching 1:1.

The drilling fluid used by this reciprocating piston pump shall not contain any chemical impurities that are corrosive to metals and rubber parts. When using mud for flushing, the recommended proportion of water and mud is between 1.03 and 1.12, viscosity of mud between 18 and 25S, silt content lower than 4%, diameter of sand particles not exceed 3mm, and PH value around 7 to 8. No tiny mud balls, weeds, leaves and other impurities are allowed in the mud.

With sophisticated structure and new materials in China and abroad, small volume and light weight, easy assembly and disassembly as well as long service life of high wear parts, this mud pump enjoys superior performance.
