Our Centrifugal Pump Products

Vacuum Truck Pumps

Cotter Marketing has partnered with System One to provide our centrifugal pumps as we believe they offer the highest quality and best reliability option for our customers. They include design features that work to mitigate the most common failure points of centrifugal pumps, making them last longer than other competing pump manufacturers.

System One centrifugal pumps offer superior performance due to the nature of their construction. They are specifically designed to work with heavy industrial capacity loads, handling greater loads than other competing centrifugal pump brands. System One centrifugal pumps include design features such as oversized bearings to increase bearing life span, saving you time and money long term on maintenance

 

Tailored Solution for Different Environments

We can deliver tailored solutions for a variety of different environments and applications to help you get the job done. Our team is on hand to help you every step of the way, from centrifugal pump sizing to the efficiency of centrifugal pump, we can find the best suited centrifugal pump for your specific needs. Our range of centrifugal pumps includes use cases such as vertical centrifugal pumps, centrifugal chemical pumps and centrifugal oil pumps. No matter the liquid, the size or the use case, our centrifugal pump catalogue likely includes the perfect fit for your needs. Feel free to get in touch with a member of our team if you’re not sure what you’re looking for, or if you are looking for a specific centrifugal pump, and a member of our team will be happy to assist in order to source the exact pump you need.

Our centrifugal pump catalogue contains a range of different centrifugal pumps in a variety of frames so that you can source the exact pump you need for your project. The different pumps are specially designed to cover a variety of applications reliably and cost effectively. As centrifugal pumps use fewer moving parts as compared to other methods of liquid transportation, they are low energy consumption and more environmentally friendly, helping you to save money both on maintenance and repair costs, as well as contribute towards reducing energy costs. In addition, our centrifugal pump selection has been specifically selected in order to be low maintenance without compromising on equipment lifespan, so that you can rest assured you are getting quality equipment that will last.

As you would expect of equipment designed for liquid to flow through, abrasion and erosion are important concerns. Our pumps have been designed to resist both in order to last longer and work effectively for as long as possible. We offer maintenance training on the centrifugal pumps we stock to help you keep your projects up and running smoothly and your clients happy.

We cater for a range of centrifugal pump sizing needs, so that big or small we will be able to find you a suitable pump to get the job done. Whether you are transporting water, sewage, petroleum or other substances and no matter the volume, our team can help you find the perfect solution for the job. We are able to handle large volume orders suitable for industrial scale projects.

 

Pump Efficiency Technology

One of the primary concerns for many engineers or project managers is the efficiency of centrifugal pumps. This is important, because efficiency also factors in to the centrifugal pump cost. The pumps we stock feature built-in technology designed to mitigate the most common wear and tear and failure issues. Our pumps feature heavy duty shafts and larger bearings, targeting the areas where 90% of failures commonly occur.

 

System One Power End Conversions

In addition to implementing centrifugal pumps in brand new projects, we also offer System One Power End Conversions. These can be used to upgrade existing pumps to utilise and benefit from the System One Heavy Duty Design advantages. This is particularly beneficial if you are looking to acquire contracts to maintain and improve existing projects, or in builds where the costs to rip out and install brand new pumps is simply not cost efficient. We provide pump solutions that cater to both new and existing projects, granting you the flexibility necessary to work with a range of projects.

 

Frequently Asked Questions


What are the parts of centrifugal pump?

A centrifugal pump consists of a few primary pieces of equipment. These are:

  • Impeller – This is a rotor that increases the kinetic energy of the flow through the pump.
  • Casing – This contains the liquid and helps direct the flow in and out of the pump.
  • Shaft – The impeller is attached to the shaft, which carries torque from the motor to the impeller.
  • Shaft Sealing – As pumps contain liquid, sealing is necessary in order to prevent spillage or leaking.
  • Bearings – Bearings come in several types, which work slightly differently from each other but all work to essentially reduce friction between moving parts and constrain the motion of the shaft.

What are centrifugal pumps used for?

Centrifugal pumps are used to transfer liquid, whether that be horizontally or vertically from a low level to a high level. There can be numerous reasons why this might be necessary, but essentially they use rotational kinetic energy from a motor to direct liquid flow along pipes in a desired direction. The liquid can be anything from water to a range of substances, such as oil or chemicals. They are commonly used in power plants and in oil refineries, where the transportation of liquid in various directions is needing for cooling or processing purposes. Having complete control over the flow and direction of liquid is a necessary function as part of the business process, and depending on the use case, issues with liquid flow can be catastrophic for business. This makes it very important to have pumps that work consistently and reliably in order to facilitate smooth operation, as faulty pumps can drastically impede normal business operations.


What are the advantages of centrifugal pumps?

Probably the biggest advantage of using a centrifugal pump as opposed to any other method of directing liquid flow is the simplicity of it. Other methods of directing liquid flow typically involve multiple moving parts. As a rule of thumb, the more moving parts present, the greater the chance there is of a piece breaking. This leads to higher maintenance and repair costs. Centrifugal pumps use kinetic energy to transport liquids, relying on simple physics concepts, which reduces complexity and reduces maintenance costs.


Why do centrifugal pumps need priming?

Centrifugal pumps need to be primed, which means that the pump casing has to be filled with liquid before the pump can be turned on. This is very important, because if it is not then the pump casing may become filled with air or vapour, which will prevent the pump from functioning correctly. If you fail to prime the pump and air enters, it can prevent sufficient suction pressure being created in order to pump liquid properly. Priming centrifugal pumps is a standard practice, but there also exist self-priming pumps, which use a variety of methods in order to work without specifically being primed.


How many types of centrifugal pumps are there?

There are different types of centrifugal pumps and they are used for a variety of purposes. Radial and axial centrifugal pumps are used to transport liquid perpendicular or parallel to the impeller’s axis of rotation respectively. There are also horizontal and vertical centrifugal pumps, which transport liquid either horizontally or vertically as one might expect.

In addition to centrifugal pumps, there are also several other pump types which provide a similar function. An example of this is a positive displacement pump. These are also referred to as, “constant flow machines” because they provide a consistent flow at a given speed regardless of discharge pressure. There are numerous design differences between positive displacement pumps and centrifugal pumps, such as positive displacement pumps having no shut-off head, which leads to different engineering requirements in pump design.
