How are You Sealing Your Slurry Pump?

The kind of seal you use for your slurry pump will depend upon whether the pump is a centrifugal pump or a peristaltic pump. It will also depend upon the fluid to solid ratio and the regulations that govern your treatment and transport of slurry.

Eliminate the Negatives

When choosing a sealing method for your slurry pump, we recommend that you consider four factors: seal life cycles, equipment design, budget and slurry characteristics. While considering these areas, identify any piece of equipment that is going to cost too much money to seal and consider replacing it first. Continue using this rationale when evaluating all equipment or protocols. If they are inefficient and costly, get rid of them.

Sealing Your Slurry Pump

Slurry Classification


Newtonian or settling slurry has properties more like fluid. It has a high fluid to solid ratio. It flows a lot better and is easier to transport. It settles particles out faster and has more water for cooling and lubricating the pump.


Non-Newtonian or non-settling slurry has properties more like solids because they have a high solid to fluid ratio. It doesn’t settle particles as easily and has less water available for cooling and lubrication.

Sealing Solutions

Since slurry equipment is large, most can be fitted with split sealing solutions which can save time, money and labour hours. Split mechanical seals can be combined with heavy-duty, non-split flushless cartridge seals, environmental controllers or, in the case of harsh, abrasive slurry, high strength mechanical packing.

Generally, the highest performance is obtained by using a mechanical seal design in which the springs are all outside the seal. Slurry migrates across seal faces and can collect there. When the springs are outside the seal, they are unaffected by migration and can continue to deliver full power.

How a Centrifugal Pump Works

On this blog, we like to provide consumer information to give you a better idea of what we offer, why we offer it and the companies we choose to work with. Sometimes, we also like to explain how things work. We know this isn’t always for everyone, but we do get questions about how various pumps work from time to time. Here is how a centrifugal pump works.

How a Centrifugal Pump Works

A centrifugal pump transports fluids by conserving the kinetic energy of rotation into hydrodynamic energy within a fluid. Usually, the rotational force comes from an electric motor or an engine. The engine or motor powers an impeller blade, which rotates within a casing or chamber. The fluid enters into the casing, where it contacts the impeller blade.

The rotational force moves the fluid radially and tangentially outward until it has been forced away from all impeller parts. The velocity and pressure of the fluid are increased by the force from the impeller. The fluid then moves into the diffuser part of the casing. Because the diffuser is smaller in volume than the casing, the fluid gains more pressure in the diffuser. The fluid, however, moves through the diffuser with less velocity.

Centrifugal Pump Applications

Centrifugal pump systems are used in the chemical and petrochemical industries to pump water, chemicals and sewage. They are also used in many other industries for sewage and water pumping.


If the centrifugal pump principle is applied backwards, it becomes a turbine. The pressure from the water coming in is converted to mechanical rotational energy.

Why a High Quality Pump is Important

Centrifugal pumps can develop problems, especially those of lower quality. These include: cavitation, impeller wear, corrosion, overheating and leakage. In addition, they must be primed. That’s why it’s important to only use the highest quality pumps for your operation, especially when failure or downtime can cost you thousands of dollars.
