What is the working principle of the VAUGHAN chopper pump?

The VAUGHAN chopper pump has several cutting stages. At the inlet, there are cutting plates, and the nut at the inlet is also a chopping component. The first stage of chopping occurs between these components. The second stage of chopping takes place between the cutting plates at the inlet and the chopper fan design. On the back of the fan, there are additional cutting sections, and an additional upper chopper is placed behind the fan. A chopping process also occurs between these two components at the back of the fan to protect the seal. This unique design ensures a “guaranteed non-clogging” feature, making it an unparalleled design.

What are the application areas of the VAUGHAN chopper pump?

Vaughan Co. is a world leader with over 50 years of experience, proven in wastewater treatment, food, paper, automotive, chemical, and petrochemical industries.

The Vaughan chopper pump, with its unique design, can transfer wastewater and sludge along with materials such as rags, fibrous materials, hair, feminine hygiene products, wet wipes, cleaning materials, animal waste, vegetable and fruit waste, wood pieces, fabric scraps, clothing, diapers, nylon, hard plastics, paint waste, and more, without clogging, by chopping them as it transfers.

If you are using a Vaughan chopper pump, you do not need an additional macerator/chopper/crusher at the front of the pump.

With over 70% hydraulic performance, the Vaughan sludge pump can handle and transfer fluids with up to 10% solid concentration, chopping them efficiently.

The Vaughan chopper pump guarantees “non-clogging” operation in all designs, including submersible, horizontal centrifugal, self-priming, wet vertical shaft, dry vertical shaft, and circulation-type pumps.

What are the advantages of VAUGHAN chopper pumps?

There are many chopper pump brands in the industry, but they often clog quickly due to dense rags and fibrous materials. However, VAUGHAN chopper pumps provide a “guaranteed non-clogging” operation thanks to their patented unique design.

The VAUGHAN chopper pump is equipped with chopping components at every stage, from the inlet to the mechanical seal. The chopping process begins between the fan and the inlet, followed by further chopping between the fan and the rear cutter. Thanks to this patented design, there is absolutely no need for an additional macerator/chopper/crusher at the front of the pump. The pump itself is a chopper with a guaranteed non-clogging operation.

In today’s world, where energy efficiency is becoming increasingly important, these pumps work most efficiently by chopping without the need for additional equipment. Unlike other brands, using these pumps results in significant energy savings in your facilities.

With their patented internal design that guarantees non-clogging, VAUGHAN pumps ensure that process stoppages never occur. Since these pumps do not experience breakdowns or stoppages, there is no labor or time loss. Thanks to their specially heat-treated internal design, there is absolutely no need for spare parts or maintenance in the short term. With all these advantages, operating costs are significantly reduced, and system efficiency increases.

Once installed in a facility, the VAUGHAN pumps work so efficiently that their presence is often forgotten due to their flawless patented design.

What are the material properties of the VAUGHAN chopper pump?

What are the capacity and other operating parameters of the VAUGHAN chopper pump?

In VAUGHAN chopper pumps, models can be selected with a maximum capacity of up to 3,000 m³/hour. The discharge pressure (head) can be selected up to 6 bar.

What are the processes in which VAUGHAN chopper pumps are used?

Vaughan chopper pumps are widely used in municipal and industrial facilities for sludge and wastewater transfer.

Municipal Applications: Vaughan chopper pumps are used as primary wastewater lift pumps. Thanks to their unique design, they prevent blockages, buildup in screens, pump clogging, seal leaks, motor burning, and stoppage issues caused by fibrous materials and rags.

Wastewater Treatment Plants: They are used as primary and secondary sludge transfer pumps, where no additional macerator or chopper equipment is needed. In these tanks, the presence of fibrous materials causes clogging in other pumps, but Vaughan chopper pumps operate seamlessly under heavy conditions.

Final Settling Tanks: Vaughan pumps are used in final settling tanks without clogging or wear problems. Again, no additional macerator/chopper/crusher is required.

Sludge Return and Excess Sludge Pumps: Vaughan chopper pumps are also used in activated sludge return and excess sludge applications without facing clogging or wear issues. Additional macerators or chopping equipment is not needed.

Sludge Dewatering Units: For decanter or belt-press feeding in wastewater treatment, Vaughan pumps offer energy savings by working without the need for a macerator and monopump. This eliminates clogging and wear issues, reducing spare part needs.

Digester Feed Pumps: Vaughan chopper pumps are used in digester feed applications, ensuring no clogging or wear problems, without requiring any additional macerator/chopper/crusher equipment.

Exchanger Circulation Pumps: Vaughan pumps are used for exchanger circulation in digesters. While other pumps face clogging issues, Vaughan chopper pumps prevent these problems, ensuring optimal sludge circulation and gas production efficiency.

Emergency Applications: In cases of flood or water surges, self-priming pump models with diesel motors can be coupled to Vaughan chopper pumps, making them ideal for emergency interventions. These designs are often used by municipal water and sewage departments.

İSKİ (Istanbul Water and Sewerage Administration): Vaughan chopper pumps were chosen for circulation pumps in the digester tanks of the Tuzla Wastewater Treatment Plant as part of an improvement project. With Vaughan pumps, exchanger and pump clogging problems were resolved.

ESKİ (Eskisehir Water and Sewerage Administration): At the Eskişehir Wastewater Treatment Plant, all mono pumps used for primary settling, decanter, and digester feeding were replaced with Vaughan chopper pumps. Since their installation 7 years ago, the pumps have operated without any clogging or need for spare parts.
