HX series of small flow chemical centrifugal pump
HX series pumps are designed in accordance with ISO/DIS9905 , and
the import and export flange dimensions conformed HG20592-97. The
structure and dimensions of the single-stage pump are defined by
the standard ofin ISO2858.
HX series pumps included single-stage and multi-stage pump. The
structure has the following characteristics:
(1) Axial suction and top discharge,
(2) horizontal cantilever,
(3) low specific speed on hydraulics flow components.
(4) Behind of single-stage pump was open structures, we could
remove the pump rotor without disassembling the pipeline and motor
by using longer coupling. The bearing house of pumps are divided into common type and
high-temperature type. Compared with the common type, the
high-temperature type has a cooling water jacket to use cooling
water to reduce the bearing temperature. According to the medium
characteristics or user requirements, the single/double mechanical seal, tandem mechanical seal,
packing seal could be selected, what’s more, Vice impeller dynamic
seal could be chosen in the single-stage pump. Sealing parts have a
jacketed cavity which could connect external cooling water or
low-pressure steam to cool or keep warm.
HX series of small flow chemical centrifugal pumps are suitable for
petrochemical, textile, food, medicine, and other industries, it
can be used to transport corrosive or non-corrosive, clean or
medium containing a small amount of solid particles. In addition,
the pumps are used for the situation of low flow or high head.
HX(D) small flow chemical centrifugal pump had won high-tech
products award in Anhui province in 2012, and get two patents of
utility model invention.
HX series pumps conform to the standards of DIN24256/ ISO2858. The
design pressure is 1.6 MPa, and the max use temperature is 400℃.

For example HXG3.2-32×2 show: Flow: 3.2m3/h, Head: 64m of two (each

Depending on the transmission medium, pump flow components will use
different materials. The following is the material for the main

Series of small flow chemical centrifugal pumps have horizontal,
single and multistage cantilever structure, axial suction and
radial discharge. For the single-stage pump, when the lengthening
flexible coupling is selected, you can replace the seal without
disassembling the motor and the pipeline.
From the motor side, the rotation of the pump is clockwise.
HX series of small flow chemical centrifugal pump are divided into
common type and high-temperature type. The common types are
supported by pump feet, lubricated by bearing grease or oil, the
allowable temperature is 105℃. The high-temperature types are
supported by pump body center, lubricated by bearings oil, bearing
house with a jacket water cooling, and the allowable temperature is
