Horizontal Split Case Industrial Agricultural Irrigation Electric
Water Pump With Engine Motor
Brief Introduction
S Series Double Suction Horizontal Split Casing Pumps are developed
by using the latest 3D CAD and CFD techniques. S pumps are of
robust, energy saving, low fluctuation in head and capacity, low
noise and easy maintenance.
S Pumps are used for delivering clean water or light corrosive
liquid with minor solid particles and short length fibers. S pumps
are wide used in the following applications: municipal water
supply, fire fighting, air conditioning, circulation, boiler feed,
irrigation, etc., especially in water supply plant, power plant,
paper mill, steel plant, chemical and petrochemical, farming. When
the pump’s wetted parts are made in duplex stainless steel(such as
Din 1.4460) or coated with SEBF(Super Epoxy Bond Fusion)coating,
the pumps can be used for delivering sea water and other type of
liquids with medium corrosiveness.
Pump Features
1. Hydraulic Design
The hydraulic design of the impeller and volute casing are achieved
by using latest 3D CAD and CFD software, followed by RP techniques
for sand casting to verify the designs. Then the metallic patterns
are prepared via CNC machining directly from drawing in electronic
format. All these efforts guarantee KPS pumps’ excellent hydraulic
performances which are normally 2~7 percentage points higher in
efficiency than the common pumps of the same size in the market.
High efficiency of the pumps demand smaller motors, so KPS pumps
save money for customers not only in the operation cost and also in
the buying cost when pump and motor being taken into consideration
together.
2. Low fluctuation in head and capacity
The impeller is of double suction design. Furthermore, the impeller
has alternating vanes on the left hand suction side and on the
right hand suction side, thus making the fluctuation in head and
capacity during operation much lower than the usual design.
3. Two Side Drive
The S pumps have shaft extension in both the right hand side and
the left hand side. This means the pump could be driven from either
side, giving more flexibility to customers’ installation
arrangement.
4. Rotor Balancing
Rotors are dynamic balanced in conform to ISO 1940/1 G6.3 before
assembled into pumps.
5. Flange Rating
Flange rating as follows
GB/T 17241.6 PN 1.0 (For nominal head <95m)
GB/T 17241.6 PN 1.6 (For 95<=nominal head <130m)
GB/T 17241.6 PN 2.5 (For nominal head >=130m)
These flanges can be matched to DIN 2533:1976, BS 4504:1989, ISO
7005.1:1992 and ISO 7005.2:1988.
Note:Other flange forms such as ANSI,JIS,AS etc., are also available if
specified in inquiry or purchase order.
6. Various Shaft Seal Option
Pack gland, single mechanical seal, double mechanical seals are
available. Customers to specify in inquiry/order.
7. Various Material Options for the wetted parts
Wetted Parts could be made in different materials to meet different
application scenarios.
Material Options for Wetted Parts
Note:Please specify the material option in inquiry/order. When your
option is different from the above table, please specify in
inquiry/order.
SEBF stands for Super Epoxy Bond Fusion, a power coating which is
sprayed on the clean and hot(above 230 ºC) metallic surface to
protected the metal from corrosion and abrasion. See below for S
pump with SEBF coating
