Horizontal Multistage Pump

D series (D, DG, DY, DM, DF) pumps are single-suction, segmented multi-stage centrifugal pumps. It has the characteristics of high efficiency, wide performance range, safe and stable operation, low noise, long life, convenient installation and maintenance, etc.

Performance range:

Flow rate: Q: 6~950m³ /h

Head: H: 33~1056m

The axial force is balanced by the balance disc. Except for the 85-67, 155-67, 45-80, 85-80, 150-100 pumps which use sliding bearings and are lubricated by thin oil,the other pumps adopt rolling bearings and are lubricated by grease.

Pump rotation direction: The rotation direction of the pump is clockwise when viewed from the motor.

The pump motor and base can be supplied as a complete set.

According to different purposes, D series can be divided into:

D: Suitable for transporting clean water without solid particles or liquids with physical and chemical properties similar to clean water. The temperature of the transported medium is 0~+80℃, the pump suction is horizontal, and the discharge is vertically upward.

DM: It is suitable for conveying liquids with a small amount of solid particles and similar physical and chemical properties to clean water. The temperature of the conveyed medium is 0~+80℃, the pump suction is horizontal, and the discharge is vertically upward.

DG: It is suitable for conveying clear water without solid particles or objects with physical and chemical properties similar to clear water. The temperature of the conveyed medium is -20℃~150℃, and the suction and discharge of the pump are vertically upward.

DY: It is suitable for conveying petroleum products without solid particles or other liquids similar to water. The temperature of the conveyed medium is -20℃~+400℃, and the suction and discharge of the pump are vertically upward.

DF: Suitable for conveying corrosive liquids without solid particles, the temperature of the conveyed medium is -20℃~+150℃, and the suction and discharge of the pump are vertically upward.

All the above types of pumps can be selected with mechanical seals or soft packing seals according to user requirements, and the material of the flow-through parts can be cast iron, bronze, stainless steel or ordinary carbon steel.
