Ordering instructions
Must provide order information:
The required pump model or user operating point flow, head, NPSH, the nature of the medium and
temperature parameters and special parameters of the basic requirement;
The pump main parts material (not to specify the configuration according to the sample delivery);
Inlet pressure (if inlet pressure >=0.6MPa, pump casing should equip with high strength material);
The shaft seal type (three are mechanical seal, injectable soft-fillings seal, special seal part, packing
seal and so on, it will delivery packing seal if it does not indicate);
The bearing structure type (select according to medium temperature and so on, it will deliver standard
fitting if it does not indicate);
Revolving direction of pump (view from the end of transmission, the revolving direction of pump is
anticlockwise. It will deliver standard fitting if it does not indicate);
Motor rotational speed, power, voltage, protection rank, insulation grade, cooling method, whether to
guard against explosions and so on;
Base: the sample 315 with the following common base frame sizes, frame sizes above 315 with a
split base or no base, please specify when ordering;
For spare parts, please indicate the name and quantity of spare parts required;
Ordering, no special requirements to flanges book list data delivery, if any special requests when
ordering;
State seal flushing method: wash the external and external washing. Add the rinse water temperature
is suitable for <80 °C in water or medium instead of water occasions. For external washing of the
water temperature >=80°C or media containing sand and other particles of the occasion;
Flat flange of the pump, with the sealing surface for sealing wire required the contract specified.
Selecting description:
The order of user isn't limited by the data which listed in the sample performance curve and
performance parameter chart, this company may design and provide the products specially
according to user's actual requirement flow and head;
If it is close to the listed performance parameter, it will prefer to select the standard impeller pump
and the high speed pump generally (the premise is that satisfies the requirement of cavitation
performance);
If user's required flow and head parameter aren't in the scope of product's large flow and low head
operating condition, the matched motor power may confirm and reduce properly according to the
actual operating condition point.
if you have special selecting or have the unclear place to the sample, please inquire the technical
support department of Shanghai East Pump (Group) Co., Ltd directly.
Recommended spare parts: shaft, mechanical seal, seal ring, packing, bearings, impeller.
