Drilling pump NB4 - 160 / 6,3
Pump type NB4 - 160 / 6,3 is intended for injection of drilling fluid into a well during exploration drilling up to 2000 m deep, carried out by rotary and rotary percussion methods. The pump is designed to operate in climatic conditions "UZ", "TZ" according to GOST 15150 - 69 at a temperature of - 50C to + 400C. The operation of the pump at temperatures below 00C must be ensured by conditions that prevent freezing of the drilling fluid. Clay solutions, emulsions and water can be used as flushing fluid. The pump is used for pumping liquids with specific gravity (density) up to 1.2 g / cm2, viscosity up to 35c, sand and sludge content up to 4.5% (by weight).
