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
