1Product Introduction:

KDFYseriesVacuum assisted trailer typeMobile pumping stationIt is a structurally novel product developed based on repeated research of similar technologies both domestically and internationally.executeGB/T 5657-1995 standard, the engine shall comply with GB1147.1 national standard.This pump set integrates self-priming and non clogging sewage discharge, using a diesel engine driven axial reflux external hybrid type, and through the unique design of the pump body and impeller flow channel, there is no need to install a bottom valve or fill water during use. The pump set can suck and discharge liquids containing large solid particles and long fiber impurities, and can be widely used in municipal sewage and flood control projects, agricultural irrigation, etc. This pump set has a simple structure, good self-priming performance, strong sewage discharge capacity, high efficiency and energy saving, and easy use and maintenance.

VIStructural reference diagram and working principle:

KDFY vacuum assisted trailer mobile pump stationIt is mainly composed of trailer, diesel engine, coupling, pump head, impeller, rear cover, mechanical seal, pump shaft, bearing seat, inlet valve, gas-liquid separation pipe, water inlet valve, inlet and outlet pipes, rain cover, vacuum auxiliary pump, etc. The structure of the pump is shown in the above figure. The working principle of the pump: There is a liquid storage chamber inside the pump body, which is connected to the reflux hole above The circulation hole below is connected to the working chamber of the pump, forming an axial reflux external hybrid system of the pump. After the pump stops working, a certain volume of liquid is stored in the pump chamber. When the pump starts, the stored liquid in the pump is ejected upwards with air under the action of the impeller. The liquid flows back to the working chamber through the grid of the gas-liquid separation tube, and the gas is discharged outside the pump, forming a certain degree of vacuum inside the pump and achieving self-priming.7Technical performance parameters:

8Product features:

The perfect combination of diesel engine and self-priming pump, coupled with four-wheel mobile trailer and outdoor rain cover, allows for outdoor operations without climate restrictions, and manual operation is availableAutomatic control.
