This series of horizontal multistage pumps use national energy-saving hydraulic model, developed and updated constantly by our factory, with the advantage of high efficiency, wide range of performance, safety and smooth operation, low noise, easy installation and maintenance, long life, and its technology level is in the domestic leading position, product performance is reliable.
1) Type D pump is used in mine and urban project for delivering clear water without solid particles or other liquids which are physically or chemically similar to clear water. The temperature of liquids are not be over 80 °C.
2) Type MD pump is used to deliver nertral water with solid particles below 1.5% (viscosity less than 0.5mm) and other sewage. It is suitable for using in steel factory and mine etc. The temperature of liquids can not exceed 80°C.
3) Type DF pump is used for delivering corrosive liquids without solid particles, the temperature of liquids is -20 °C ~105 °C.
4) Type DY pump is used for delivering oil and pertroleum products without solid particles and viscosity below 120 centistokes, the temperature of liquids is -20 °C ~150 °C. The inlet pressure of all above pumps is less than 0.6Mpa.

During the daily use of the self-priming pump, there will be some more common problems. For example, the self-priming pump's non-pumping problem will be caused by many different reasons, so how do we deal with these problems is the key. The reasons why the self-priming pump does not pump water include the following aspects.
The hot water submersible pump is used for hot spring bathing, and can also be used for extracting groundwater from deep wells, and can also be used for water lifting projects such as rivers, reservoirs, and canals. It is mainly used for farmland irrigation and human and animal water in high mountain areas. It can also be used for central air conditioning cooling, heat pump units, cold pump units, cities, factories, railways, mines, and construction site drainage. The general flow rate can reach 5~650m³/h, and the head can reach 10-550 meters.
Diaphragm pump is a new type of conveying machinery that can convey various corrosive liquids, liquids with particles, high viscosity, volatile, flammable, and highly toxic liquids. Diaphragm pump has four materials: plastic, aluminum alloy, cast iron, stainless steel.
