3. Common Typical Applications
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.

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

5. 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.
