The CEMO
highly efficient
multistage pumps are manufactured with the highest grade
of certified materials and ultra-precise machining. The
Clearwater range includes our CPH 480, CPH 505, CPH 530,
CPH 540 and our CPH 580 pumps. These high flow (415
m3/hr 888 m3/hr) pumps can be used with a range of
pressures provided by the number of stages in series.
(Up to 120 Bar.)
Materials of construction are
sand and die cast PB1 Phosphor bronze impellers,
diffusers, shaft sleeves, neck rings, neck bushes,
balance and counter disc components. All stage casings,
suction and delivery covers are cast from A-2 Steel or
Gr17 Cast Iron or SG42 nodular iron as per customer's
requirements. Anti-abrasive coatings such as HVOF
tungsten carbide, ceramic coatings and chrome plated
coatings are used on wear susceptible wetted components
or rotating element assemblies.
All rotating element
individual components and assemblies are balanced to ISO
19401 prior to assembly. All pump shafts are
non-destructively tested and heat-treated to relieve
residual stresses. Pump bearing types include either
white metal shell types or branded roller bearing types
dependent on pump type and model.
We also refurbish various
other OEM multistage type pumps with our extremely high
quality machined components which are interchangeable
with these pumps, as well as innovative hydraulic
improvements for enhanced pump performance and
efficiencies. Independent test results showing
improvements are available on request.
Our in house foundry and all
on site machining undertaken on our premises ensures
speedy delivery of a quality engineered product. All
processes follow our accredited ISO 9001:2008 quality
standard. Independent pump testing is carried out at the
South African Bureau of Standards (SABS) and all pumps
are tested to ISO 9906:2012 Grade 1 standards unless
otherwise specified by client.
On site commissioning and
pump condition monitoring are carried out b y our field
service engineers and technicians who are available 24
hours/day, 7 days a week for commissioning and breakdown
services. On-site pump repairs to wear faces, balance
valve assemblies are also carried out by the same team
of pump experts. Pump condition monitoring is also a
service offered by our pump field service team on either
a monthly or fixed periodic basis. Monitoring includes
pump flow readings, pressure readings, energy
consumption and overall efficiency. |

Crown 120 and Crown 737
are an underground
industrial standard
known for their mud
pumping abilities with
SG s of up to 1.2. The
high flow (up to
44m3/hr) and high
pressures (up to 225
Bar) achievable on these
pumps are what make them
perfect for underground
mine mud transfer as
well as sewage plant
sludge movement. These
pumps are also
extensively used in
steel mill plate
descaling, mud drilling
and for pumping light
tar s and resins within
the petro-chemical
industry. Materials of
construction include
fabricated steel casings
with bronze crosshead
wear liners, nodular
iron eccentric and
connecting rods
transferring the fluid
via steel, thermally
coated plungers through
forged steel fluid ends.
Eccentric drive is via
heat treated jackshaft
pinions on eccentric
ring gears. The pumps
recommended slow
eccentric speed (120
rpm) ensures pump
reliability and wear
component longevity. |
