DDM series multi-stage horizontal centrifugal pump
is used to deliver the mine pulp or mine drainage over
long distance, its medium size is less than 2 mm, weight
concentration is less than 20% and water temperature
is less than 80 ℃.
The pump impeller is back -to-back symmetrical
arrangement , and its balance device is canceled, so
the auxiliary pump in the working room can not be
installed to supply the balance device to overflow
water .We use cast steel to manufacture the wetted
parts , and all the wearing places are painted
antifriction alloy , so it has such advantages as
high efficiency , wear resistant and long life, etc..
DDZ series pump is improved from DDM series, so
its loading capacity is double than DDM series and
its inlet pressure can reach up to 10 Mpa, this series of
pump can be used in hydraulic coal mining for
pressurization. Installation dimension of this two
pumps is same , so their wearing parts can be
interchangeable and can achieve the effect of
multi-usage.Under the conditions of bad water (solid
particles is 30 g/L and particle size less than or equal
to 0.5 mm), the pump can continuouslywork for 5000 hours.
Meanings of pump type : e .g . DDM360-75
DDM - Symmetric multi-stage coal and mud pump
360 - Capacity of the designed point
75 - Single stage head
10 - NO.of stage
