Compact
structure: Pump casing: the spiral casing with pipe connection is
designed and manufactured by the most superior hydraulic model
nowadays, with inlet and outlet in a straight line and of the same
diameters. Flanges conform to GB***6.5, and are equipped with Rp1/4
or Rp 3/8 pressure testing hole.
Impeller: closed cast iron impeller and no limit to rotation
direction under the water temperature below
*0 and
**0centigrade. Special
design of rotating seal ring to ensure high seal
dependability.
Directly connected by motor, complete
concentricity of motor and pump shaft, little vibration and low
noise.
Same inlet and outlet diameters in a straight line, so that it can,
just like a valve, be mounted at any a position in pipeline
Specially structure bearing using a whole shaft for dependable
operation
The operation conditions of mechanical seal improved by compulsory
circulating flow, thus to lengthen the operation life of mechanical
seal.
Vertical installation structure to greatly lessen the floor
occupation of pump, saving construction investment by
****0%
Application
ZLG for the transportation of non-corrosive cold and hot
water in the fields of air condition, heating, sanitary water,
water treatment cooling, refrigerating system, liquid circulation,
water supply, pressurization and irrigation etc.
Most application for modern constructions.
