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.

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.
