Circulating slurry pump

Overview

NPY is single suction, horizontal oil slurry pump with centerline mounting and double casing, which is fully lined, available in one stage or two stages impeller. The pump is engineered for transferring high temperature medium containing catalyst solid particle in FCC or DCC process,also  handing in general chemical process transferring abrasive or erosive medium.

MAWP: 50 bar/725psi

Temp: 420℃/788'F

Rotation: CCW seen from drive

Orention: end - top (OH2), top - top (BB2)

Structural characteristics

1, Double casing structure. Robust outer casing is pressure casing, which is designed as per API 610 with guaranteed 20 years lifetime. The material of inner casing withstands wearing and corrosion of pumped medium.

2, Heavy duty and centerline mounting outer casing.

3, OH2/BB2 type structure, optimized on maintenance.

4, Advanced hydraulic design, close type impeller, inducer is available, efficent performance, low NPSHr.

5, Optimized balanced hydraulic design with proper sizing on thrust bearing.

6, BVearing bracket and seal housing with cooling system ensuring reliable operation of high temperature application.

7, Oil mist lubrication with proper auxiliary system dealing with tough ambiance.

8, Use flexible disc coupling ensuring upmost transmission condition.

9, Cartridge bellow seal with proper auxiliary system as standard to handle critical operating condition
