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

5.3.3,
5.5 Twice Table 4 Nozzle Loads…
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
to 5.8.11. Seals and sealing systems in
compliance with API 682 can be
supplied at extra price.
5.10.2.2 The bearing...housings shall be
equipped with constant level sight feed
oilers ...
Oil circulation is ensured by the
pumping – effect of the angular contact
ball bearings .

< 0.04mm/m, 0.08mm maximum
0.13mm maximum offered
8.3.3.3 The pump shaft shall be one piece,
unless otherwise approved by
purchaser.
Above certain pump length, a multiple
shaft arrangement is used for ease of
maintenance.
span limit of 1700mm, above this
separate shafts are provided to ease
shipping.
