Slurry Pump Drive Types

There are two kinds of drive types between slurry pumps and motors. One is the DC type that ismotor and slurry pumps are connected via coupler. The other is the V-belt drive ( motor and slurry pumps are connected via belt and pulley).

According to different parameters, we can decide different drive types for sludge pumps. Within therange of specified flow and head, we can know the speed of sludge pumps. Generally, when the slurrpump speed is the same with the one of motor, we will select the DC type. Otherwise, we will select theV-belt drive type which include the DC, CV(Z), CL(Z) ， CR(Z), BD,ZV(Z). And V-belt drive type is alsoused when the centre distance between two shafts is large.

CRZ drive: The motor is on the right side of the pump when viewed from the inlet of the pump.

CLZ drive: The motor is on the left side of the pump when viewed from the inlet of the pump.

CV drive: Also known as back-to-back drive. The motor is mounted above the bracket that is connected to the pump shaft. This type of transmission saves floor space. The pump is on the same side as the shaft end of the motor.

ZVZ drive: Also known as tailstock belt conveyor. As the name implies, the motor is attached to the shelf at the end of the pump and the belt is located between the pump and the motor.

DC type: sludge pumps is reliable with lower failure rate. lt will not lose the speedAnd it is with high efficiency. But its speed is fixed, its work range is not wide.

When overloaded, the belt will slip on the pulley to prevent damage to weak parts and provide safetyprotection to weak parts. V-belt can easily fit variable sludge pumps operation parameter, and it can bewith wide pump selection range. But wil loose the speed and with lower transferred efficiency . And it isnot more reliable than the DC drive type

The two drive modes have their own advantages and disadvantages. When we select the drivemodes for slurry pumps, we do not only consider the pump speed and motor speed but also consider thespecific requirement of the site.
