Vertical Sump Pumps, CPXV or ECPJ

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

• 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

CPXV ECPJ

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.

ECPJ Closed multivane impeller with front

wear rings and back vanes.

ECPJ - R Closed multivane impeller with

front and back wear rings (API 610).

ECPJ - O Open multivane impeller with

back vanes (optional with wear plate).

ECPJ - F Free flow impeller with back

vanes

Cannot be met on the casing, but

available on soleplate discharge.

5.7.1 Impeller pumping vanes ...shall not be

used to balance the thrust

Closed impellers use front and back

wear rings to balance the thrust,

however if semi open impellers are

specified, these will use back vanes

5.8.1 Mechanical seals and sealing system in

accordance with ISO 21049 (= API

Standard 682)

Standard Cartridge seals meet par. 5.8.2
