Gorman Rupp Pumps

When you need a pump that can handle demanding duties without becoming difficult to maintain, Gorman-Rupp is a proven option. We supply this range across New Zealand for solids handling, dewatering, process transfer, petroleum transfer, and other tough fluid movement applications.

As a New Zealand owned and operated pump company with more than 100 years of experience, we focus on reliable products backed by practical support. Our goal is to help customers find the right pump for the job without overcomplicating the process.

We have chosen to represent Gorman-Rupp because the brand is known for quality, reliability, engineering, and strong after sales support. That matters when you are not simply buying a pump, but investing in equipment that needs to perform consistently in real working conditions.

What Gorman-Rupp Pumps Are Used For

Self-Priming Pumps

Gorman-Rupp is especially well known for self-priming pumps, and this is one of the strongest parts of the lineup. Our Super T Series is suited to handling solids, corrosive liquids, and slurries. Alongside that, we also supply U Series pumps for customers who need broader self-priming options across different duties.

Dry-Prime Pumps

Where dewatering is the priority, our priming-assisted range gives you another option. The VPA Series Dry Prime Pumps are positioned for applications that do not require higher head and higher flow, while the PA Series Dry Prime Pumps are suited to customers looking for a dry-prime setup for more demanding dewatering work. We also carry the PAH Series Dry Prime Pumps and the PA Series Silent Pump for jobs that need the same style of setup in other configurations.

Positive Displacement, Process, and Petroleum Pumps

Gorman-Rupp is not limited to self-priming and dewatering duties. We also supply Large End Suction Centrifugal Pumps and Petroleum Pumps. This gives you a wider set of options for jobs involving fuel, petrochemicals, solvents, larger process duties, and more difficult industrial liquids.

Aeration and Wastewater Support

Our range also includes products that support the wider pumping system. The ECH2OSTORM Venturi Aerator is used where aeration and oxygen transfer are part of the overall process, rather than just moving liquid from one point to another.

Key Features of Gorman-Rupp Pumps

Built around practical pump design

Gorman-Rupp pumps are designed with practical operation in mind. Across the range, the focus is on dependable performance, straightforward servicing, and pump designs that are built to keep working in demanding conditions. That makes them a strong option where reliability matters just as much as pump performance.

Priming systems designed for reliability

A key strength of our range is the way different models approach priming. The Prime Aire system is designed to provide reliable priming without the leaks commonly associated with traditional vacuum-assisted pumps, while other parts of the range are built around self-priming performance. This gives customers more flexibility depending on the type of pump setup they need.

Eradicator solids management for tougher duties 

Selected Super T Series pumps are also be fitted with the Eradicator solids management system. This is designed to help deal with stringy materials that can increase the risk of clogging in tougher wastewater and solids handling applications. The system uses a self-cleaning wear plate with notches and grooves, along with a lacerating tooth that helps break up debris and move it through the pump more effectively. It also includes a lightweight cover that makes impeller access easier when inspection is needed.

Easier access for maintenance

Gorman-Rupp also stands out for serviceability. The 10 Series is designed so a clog can be removed through the cover plate opening without disturbing piping or using special tools. Their large flow pumps make side access port easy for cleaning and inspection, along with a double volute design that helps protect against shaft breakage. These are practical details that can help reduce downtime when maintenance is needed.

Material options for tougher conditions

This brand also offers a broad spread of material options across different models. Materials include Bronze, Cast Iron, CD4MCu, Stainless Steel, and Ductile Iron. This gives the range greater flexibility where liquid type, site conditions, or durability requirements call for something more specialised than a standard pump construction.

A wider range than standard transfer alone

Alongside self-priming, dry-prime, process, and positive displacement pumps, our range also includes products such as the ECH2OSTORM Venturi Aerator. That gives customers access to a broader solution set where the system needs to do more than basic liquid transfer.

Frequently Asked Questions

Are datasheets available before I make an enquiry?

Yes. Many of our product pages include downloadable datasheets, so you can review key technical details before getting in touch. That makes it easier to compare options and shortlist the right pump for your application.

What makes the Prime Aire dry-prime system different?

Prime Aire system uses a venturi and compressor instead of a traditional vacuum-assisted setup. It’s oversized, oil-lubricated mechanical seal allows continuous dry running without damage, which is a strong advantage on dewatering jobs.

Do you have options for petroleum products and solvents?

Yes. We supply Gorman-Rupp RD and RS Series Roto Prime pumps, which are specifically designed for pumping petroleum products, petrochemicals, and solvents. The Roto Prime design quickly evacuates air and vapour, making it well suited to transfer duties like off-loading and hose stripping.

Can Gorman-Rupp gear pumps handle thicker or harder-to-pump liquids?

Yes. The G Series gear pumps are designed for a wide range of difficult liquids, including oil, diesel, kerosene, molasses, syrup, dough, tallow, bitumen, glue, and paint. That makes them useful where a standard transfer pump may not be the best fit.

What if I need urgent pump support outside normal hours?

We offer emergency pump support 24 hours a day, 365 days a year. Our technicians are prepared to respond quickly to breakdowns, urgent pump issues, and unexpected demand so downtime can be reduced as much as possible.
