Regular mud pumps and other machinery for inspection, maintenance, early occurrence of the problem to be addressed in order to avoid downtime. Construction should pay attention to sediment particle size, we should always check the mud pump large particles when wearing parts for timely repair or replacement. The main components are easily damaged mud pump is the pump casing, bearings, impeller. The use of advanced anti-wear measures to improve the life of wearing parts, which reduces investment projects, improve production efficiency. While standing wearing parts should be to prepare for the timely replacement. 2NB12 / 4-15 mud pump parameters:?
