QY oil-filled submersible pump

Oil-filled submersible pump is cooled and lubricated by machine oil. We manufacture two categories of electric oil filled submersible pumps. They feature oil-filled three phase submersible motor. One category is QY series and QJD series stainless steel oil-filled submersible well pump, designed for clean water. But the other category is WQ series submersible sewage pumps, designed for sewage water. All of our WQ series are oil-filled submersible pumps except for WQS, because WQS is a water-filled submersible pump.

QY oil-filled submersible pump features

In this page, we will only introduce QY oil-filled submersible pump in detail. We will introduce the other series of oil-filled submersible pumps separately in their own page. QY series are small submersible pumps because their power range, head and flow quantity are all small. They have single stage of impellers or more stages of impellers, depending on the need of clients.

The applications of QY series is similar with that of QJ series submersible well water pump. But QY is relatively smaller. It is especially suitable for shallow boreholes and open wells, smaller rivers and lakes. The general working conditions for QJ series deep well submersible water pump apply to QY series too. The structure of QY is also same as that of QJ, except the motor part. For oil-filled submersible pump, please remember to replace the lubricating oil regularly.

Oil-filled vs water filled submersible pumps

Talking about oil filled submersible pump, many people cannot help comparing it with water filled submersible pump. There is not too much difference between them. Both stand upright, and we can install them in different angles. The major difference is the cooling way of electric motor.

People may worry that if oil filled submersible pump leaks, it would pollute water. Because a water-filled motor has clean water inside, so if it leaks, it leaks only clean water. But an oil-filled motor has oil inside. If it leaks, it will leak oil. Therefore, it would cause pollution to the water it is pumping.

But don’t worry, we have taken measures against that risk. Our QY series submersible pump oil type uses machine oil. In order to prevent pollution, we have used high quality mechanical seal. This seal will effectively prevent leakage. For QJD series, we have used food-grade white mineral oil to replace machine oil. WQ series is for waste water. Although there is no concern about pollution in case of WQ series, we still protect them well from leakage.
