The cementing pump 9T (NC-320)
The
cementing pump 9T (NC-320) — two-piston
bilateral action.
Assignment - for a
forcing (clay, cement, salt) solutions at flushing
-pressing works and at cementation of
oil and gas holes.
Piston cementing mud
pump NC-320 is developed on the basic of the mud pump
9Т, the basic details and assembly's units of mud
pumps are similar and interchangeable.
