Multistage Surface Pump (MSP)The MSP pump features a field repairable thrust chamber that does not require pump or motor removal for maintenance. It is designed using proven bearing arrangements as used in the established centrifugal NOV pumps.
The MSP thrust chamber also incorporates a patent pending seal system which uses Balanced Type 1 mechanical seals. The mechanical seal, located in the fluid end is completely separated from the thrust chamber, preventing any cross contaminations should seal leakage develop. |
