Frequently Asked Questions

Hydro Innovations is the only authorised distributor for all the municipal and industrial markets in Australia. We stock hundreds of Gorman Rupp pumps in Australia and all of the major spare parts required for maintaining them.

A self-priming pump only requires water in the casing to develop a vacuum (by the impeller turning in the casing) to prime the pump. This is done without the need for a foot valve and without having to fill the suction line. An “auto-prime” (also known as a “dry-prime” or “vac-prime”) pump does not need water in the casing, however, it does need the air separation chamber, priming system belts (driving either a compressor, vacuum pump or diaphragm pump) and the non-return check valve to be in working order (if not, the pump won’t prime). This style of pump is best for “manned” operation, where trouble with any of these components can be addressed quickly. A self-priming pump is the better choice for “un-attended operation”.

A guaranteed “re-primer” is a self-priming pump that is guaranteed to re-prime the suction line after each pumping cycle even if siphoning has occurred because of solids holding check valves open, draining the casing of half of its water. Most self-priming pumps can prime a dry suction line with a full casing of water. Most of these will not re-prime automatically if a siphon event has taken place (a regular occurrence when pumping solids in the likes of wastewater). Gorman-Rupp has three model ranges that “guarantee” re-prime. Our Ultra V, Super T and Super U Series pumps are guaranteed to re-prime even after the most severe siphon event. This is critical in unattended pumping operations.

Gorman-Rupp spends millions of dollars on R&D into their self-priming pumps and manufactures them to exacting tolerances. Each component has a + and/or – tolerance to ensure that all components fit perfectly together and work in unison as a complete pump to deliver the published performance. “Copy-cat” manufacturers buy a Gorman-Rupp pump, pull it apart, and [attempt to] copy all the parts. The trouble is, they don’t know the +/- tolerances, so can’t guarantee the repeatability of pump construction time after time. They also will almost certainly not guarantee that their pumps will test to AS2417 Grade 2 (even though their curves look (miraculously) identical to Gorman-Rupp curves). What looks cheap in the beginning, can turn out to be very costly.

A Gorman-Rupp pump can be mounted at ground level, not in the wastewater 6-7m below ground. This means monitoring, maintaining, removing blockages etc can all be done at ground level, by one person and without the use of cranes. This is safer, easier and more cost-effective over the life of an installation. For more information on this, see our white papers on the subject..

We keep a large range of pumps and spare parts in stock.  This includes all common parts for common models and we can generally ship same day.  For any spare parts weighing 60kg and under we have a weekly FedEx service to have them shipped in.

An Eradicator system is a patented system used in Gorman-Rupp’s Super T Series wastewater pumps to greatly reduce blockages by stringy materials such as rags and wet wipes.

The EDUR pump draws atmospheric air into its suction line, shears and mixes it with the water being drawn from the DAF plant, and under pressure, dissolves the air into the water. The water is then re-injected into the DAF tank, where dissolved air comes out of solution to form micro bubbles which then adhere to fats, oils and greases in the water, floating them to the top. There, the grease layer can be mechanically scraped away.

Yes. We can package any of our pumps into systems containing valves, interconnecting piping, controls, acoustic enclosures etc.

Our products offer safer, more cost-effective tailored solutions in the following areas:

Cedar Meats Australia very happy with Hydro Innovations pump solutions

Reduced energy consumption with innovative DAF Pump for Waste Water Management

Cedars Meats were impressed with the simplicity of the dissolved air flotation system and promptly arranged the purchase of an EDUR DAF pump. They have been pleased with the positive results, which include:

  • A higher rate of solids removed
  • less power used for the job (reducing power costs)
  • less complicated controls
  • low maintenance future ahead for the system

Gorman-Rupp T Series and Super T Series self-priming centrifugal pumps have been successfully pumping municipal and industrial wastewater for over 5 decades. Over the past few years, with the introduction of wet-wipes and higher safety standards, the need for “choke-free” pumping has led to the development of pumps able to handle wipes, rags, rope, undigested hay and other stringy materials better.
Introducing the Eradicator Plus, for those extreme-duty applications where debris like trash bags, wipes, mop heads, rags, hair, industrial by-products, and agricultural wastes are present. Specifically engineered for cutting and tearing organic solids that enter the pump, the Eradicator Plus is Gorman-Rupp’s most aggressive solids-handling pump.
The Eradicator Plus is equipped with a continuous vane impeller in hardened iron, and an extra-thick G-R Hard Iron wearplate which is equipped with an oversized lacerating tooth that is designed to cut and shred organic solids before they enter the interior of the pump.

Advantages include:

  • Ability to mount high and dry above the wet well [not in it]
  • Self-priming to 7.6 metres
  • Low cost of ownership
  • Greatly reduced OH&S issues
  • Cut and shed solids that would block other pumps
