Type of submersible pumps

By solid handlings

The different types of liquid

When we think about dewatWhen we are choosing a submersible pump for drainage, the first consideration is the nature of the liquid being pumped. Important factors to consider include general composition, the concentration and size of suspended particles as well as the liquid’s pH level, temperature, and chemical content. For example, is it water with fine particles or a much thicker fluid, and how aggressive a media is it? The different types of liquid can be seen below.

What is drainage?

Clean water or water containing small solids such as sand or clay with a solid weight of approximately 10% and particle size up to 1.27cm diameter

What is slurry?


Semi-liquid mixtures typically loaded with sediment and fine particles of materials such as manure, cement or coal. Slurry has a solid weight of approximately 70% and particle sizes up to 6.35-centimeter diameter.

What is sludge?

Viscous mixture of liquids and solids, including soft wet mud and by-products of industrial or refining processes. Sludge has a solid weight of approximately 40% and particle sizes up to 5.08cm diameter.

The higher concentration of solids is best handled by slurry pumps which are specially designed for handling corrosive and abrasive media. If the liquid is particularly aggressive then ensure the pump is robust and designed with protection features such as hardened, clog-free impellers and wear-resistant.
