OVERVIEW

PRODUCT DESCRIPTION

The pump is divided into horizontal installation and vertical installation, the pump shell is horizontally separated from the axis, the upper part is the pump cover, the lower part is the pump body, the suction inlet and outlet are on the pump body below the pump axis, and the center line of the impeller is perpendicular to the axis. The seal of the pump can be sealed with packing or mechanical seal.

The middle opening pump at high temperature adopts the centerline support structure.

The general assembly of the bearing part is the grease lubrication bearing part, and the high lift pump and the high temperature hot water pump are the thin oil lubricated bearing part with water cooling jacket structure.

The seal forms of shaft seal are packing seal and mechanical seal.

Can adopt lubrication and shaft lubrication, the pump runs stably and the high efficiency area is wide.


FEATURES AND ADVANTAGES

The double suction pump enters water from both sides, and the pump has good cavitation performance, high efficiency and energy saving.

The utility model has the advantages of simple installation, convenient maintenance and compact structure.

During maintenance, there is no need to disassemble the inlet and outlet pipes, open the pump cover, and the rotor can be taken out for maintenance.
