I. Product Overview
The design of the entire structure of the pump is bold and innovative. Independent bearing body and support are
used to solve the problem of supporting the vertical pump with motor bearing; the impeller developed based on
excellent hydraulic model is used to solve the problem of big axial force of vertical pump; Y series standard general-purpose motor is used to make it convenient for the user to replace the long motor shaft of the vertical pump; and
the completely easy-to-remove structure will facilitate the replacement of bearing, mechanical seal, impeller, pump
spindle of high-power pump.
Compared with similar domestic products, this pump has such irreplaceable advantages as steadier running,
longer service life, more convenient replacement, easier maintenance, etc. Among vertical pumps, this product
has advanced technology and is the most ideal substitute for ISG type vertical pump, IS typecentrifugal pump,
S type double entry pump, etc.

Pump body: The spiral type pump body is designed and manufactured based on optimal modern hydraulic model.
Its flange
is consistent with the standard of GB4216.5, with Rp1/4 or Rp1/8f pressure measuring pipe.
Impeller: It is made of closed-type cast iron. The excellent hydraulic model and special structure ensures the
efficiency of the pump and can
reliably eliminate the axial force.
Mechanical seal: maintenance free at a water temperature of below 150℃, without rotation limitation. The special
design can ensure the compensatory and sealing performance of the rotating ring.
Pump spindle: The optimal design integrates pump spindle and coupling, which reduces the size of the drive
shaft and that of the pump, so that the pump can operate in a safer and more reliable way.
Pump bearing: NTN or NSK precision bearing is used, with low noise and long lifetime.
Motor: Y or Y2 series squirrel cage AC motor, BS type. Standard general-purpose motor is used to facilitate
maintenance, and high-power pump is equipped with lubrication hole for maintenance of bearing.
II. Technical Features
1. The vertical structure is convenient for installation and debugging; the specially designed motor and pump body
are connected by coupling, with high concentricity and machining precision, and less floor space helps to reduce
30%-60% of the cost of pump room. The stable seat, compact structure, and elegant casting and appearance
make the vertical type centrifugal pump full of artistic charm.
2. Y series standard general-purpose motor from a well-know manufacturer is used to ensure stable and
low-noise running.
3. Famous-brand precision bearing is used, with high precision, good reliability and long lifetime.
4. Excellent self-balancing axial force hydraulic model is adopted for impeller, greatly prolonging the lifetime of
pump bearing and mechanical seal.
5. The bearing inside the motor bearing seat is equipped with oil filling hole and drain hole, which is convenient
for maintenance.
5. The removable hard intermediate coupling eliminates vibration and noise during pump starting. The rotating
components have reliable safety protection cover.
7. The mechanical seal made from stainless steel, tungsten carbide and fluorine rubber can withstand high
temperature and pressure, has long running lifetime, without leakage and shaft abrasion, which can ensure
a clean working environment.
8. The pump cover is specially designed. The bearing seat can be taken out conveniently by removing the hard
intermediate coupling and pump cover nut. For such assembled components as pump cover, pump spindle,
impeller, etc., mechanical seal and impeller need to be replaced, and disassembly of the motor, pump body
and pipes is not necessary, thus maintenance is convenient and rapid.
III. Application
The product has a wide scope of application. It can be used to transmit different media including water or
industrial fluid, and can be applied at different temperature, flow and pressure.
The typical applications include:
Water supply: Water works filtering, transmission and separate water supply, and pressure boost of main pipe
Industrial pressure boost: process water system, cleaning system
Industrial fluid transmission: boiler water supply, condensation system, cooling and air-conditioning system,
machine tool, acid/alkali transmission;
Water treatment: distillation system or separator, swimming pool, etc.
Farm irrigation, petrochemical industry, medicine and sanitation, etc.
