• General

Compared with other similar pumps， Model - S horizontal medium -open pump is featured with long life， high efficiency，reasonable structure，low operating cost， convenient installation and repair， etc. It is an ideal pump for fire fighting， air - conditioning， chemical， water treatment and other industries.

• Pump body

The designed pressures of the pump are 1.6 Mpa and 2.0 Mpa. In order to meet different users’requirements around the world， the relevant inlet and outlet flanges of pump body can be chosen according to ANSI， PN and JIS standards. These inletand outlet flanges are all installed in the lower part of pump body， so the rotor can be taken out without disassembling pipelines of the system， and it is convenient to repair. Part of the pump body adopts a double - flow -passage structure in design， which can lower the radial force and extend the life of the mechanic seal and the bearing.

• Blade wheel

The hydraulic design of the blade wheel uses the up -to - date CFD technology， which can improve the hydraulic efficiency of the pump. The blade wheel has been made in a dynamic balance， so as to make sure that model -S pump can rnvery smoothly.

• Shaft

The diameter of the shaft is big， while the gap between bearings is short . This can lower the deflection of the shaft， so as to extend the life of the mechanic seal and the bearing.

• Shaft casing

For model -S pumps， the shaft casing can be made of many different materials， so as to protect the shaft from corrosion and abrasion. The shaft casing can be replaced.

• Abrasion ring

A replaceable abrasion ring is instaled between the pump body and blade wheel， so as to protect the pump body and blade wheel from abrasion. It is convenient to ｒｅｐｌａｃｅ. This results in low maintenance cost，guarantees enough running gap and high efficiency.

• Stuffing

The pump with unique stuffing design can use not only stuffing， but also mechanic seal. The seal device can be replaced without disassembling pump cover.

• Bearing

The unique bearing design makes it possible that the bearing can use either grease or thin oil for lubrcation. The designed life of the bearing can be up to more than 100， 000 hours. A double - row thrust bearing or closed -type bearing can also be used.

• Materials

According to actual demands of users， the materials of model -S hori-zontal medium-open pump can be copper， cast iron， nodular cast iron， 316stainless steel， 416 stainless steel， duplex steel. Hastelloy，monelmetal，Titanium alloy， 20# alloy，etc.

• Installment mode

Model - S pump can be installed in two ways： horizontal and vertical installments. The vertical installment can save floor space.
