Vertical Sump Pumps, CPXV or ECPJ

Vertical Sump Pumps, CPXV or ECPJ Common Pump Description

• Industrial & Chemical Sump Pump • API 610, VS4/5 • Single stage suspended • Radially split Sump Pump

Common Typical

Applications • Chemical industries • Petrochemical industries • Refinery offsites

Common General description

The CPXV and ECPJ pump lines are based on there own modular system, providing maximum design flexibility. With this system, each pump can be custom engineered for individual applications lengths and atmospheres.

Brief Histories

CPXV

ECPJ

• Developed using • Developed using hydraulics from CPX, MK3 & hydraulics from ERPN D-Line • Manufactured in Brunn • Manufactured in Newark since 1970 since 1990 • Worldwide population of • Worldwide population of approx 1200 pumps approx 2000 pumps • Current rate of production: • Current rate of production: 100 per year 260 per year and growing!!

Basic designs Standard (CPXV & ECPJ) - for handling products in chemical or petrochemical industries, refinery offsite

Steam heated

(CPXV & ECPJ) - for handling liquid sulphur.

Cantilever type

(ECPJ Only) - for all applications where no external lubrication or flushing is allowed e.g. hot and dirty liquids, molten salts, liquids with tendency to crystallize or became viscous.
