10 Series

The Gorman-Rupp 10 Series grey water pump range of self priming centrifugal pumps and effluent pumps have been delivering excellent service to industry since 1946. With large inspection cover to access pump internals for service or blockage removal and a very thick vaned solids handling impeller, 10 Series pumps are the choice for many an abattoir, concrete batch plant or chemical plant. Advantages include:

  • Size: 1-1.5″, 2″, 3″, 4″, 6″, 12″
  • Priming: Self priming pump. Not re-primer.
  • Application: Effluent to Industrial trash/wastewater pump

10 Series Grey Water Pump – Special Features

Heavy Duty Impeller
Gorman-Rupp 10 Series grey water pumps have heavily constructed two-vane semi-open impellers to handle heavy duty abrasive and or corrosive wastewater pumping applications. Depending on the model, these grey water pumps will handle up to 75mm spherical solids and have “pump-out” vanes on the back of the impeller to reduce foreign material build-up around the seal area.
centrifugal pumps
Multiple seal Options
10 Series pumps are available with many seal options to meet the needs of each application. Gorman-Rupp’s exclusive tungsten titanium carbide faced, double floating, self aligning, oil lubricated seals are recommended for all the tough jobs. Double mechanical grease seals or self-lubricated mechanical seals in various materials are also available for less demanding applications.
centrifugal pump
Removable Cover Plate
A large removable cover plate on 10 Series grey water pumps allows quick and easy access to pump internals without needing to disconnect piping or drives. Blockages can be cleared quickly, and impeller, wear plate and seal can be readily accessed for inspection and service.
peristaltic pump
Replaceable Wearplate
Gorman-Rupp 10 Series wastewater pumps have replaceable wearplates which fasten to the cover plate and may be replaced in minutes. No expensive castings to replace.
submersible pumps

Self Priming

Gorman-Rupp 10 Series pumps are self priming, requiring no add-on priming systems. After being filled with liquid, the 10 Series pumps are guaranteed to prime on suction lifts up to 7.6metres above the liquid level.

10 Series pumps are ideal for continuous, automatic operation in industrial wastewater or effluent pumping duties.

 

High and Dry

Gorman-Rupp self priming centrifugal pumps can be mounted “high and dry” above the sump liquid level. No need for (submersible) pumps to be in the liquid being pumped (wearing and corroding from the inside and the outside). This means there are no guide rails to maintain, no [leaking?] discharge bend to maintain/replace, and no need to open wet well lids and expose operators to falls.

Self priming pumps also virtually eliminate confined spaces issues and eliminate the need for lifting devices such as cranes or hoists, because pumps are at the surface [ground level], so are easy to access for monitoring and maintenance.

Reduced WH&S

Using Gorman-Rupp self priming pumps can reduce WHS issues associated with pumping applications. Because pumps are located at “ground level”, high and dry above the wet well [not in it], pumps are easily accessed by operators for monitoring, maintenance or repair. Some of the identified risks that can be reduced or eliminated include:

        • Working over water
        • Working at heights
        • Working with cranes
        • Working with heavy swinging weights

Other OH&S issues can also be eliminated with the use of self primers. Unlike submersible pumps, self priming pumps do not need guide rails and discharge base elbows that will need service and replacement over the life of the installation, requiring confined spaces entry and the associated dangers. Submersible pumps also need chains to raise them to the surface. These chains can become corroded and weakened over time, creating a potential danger to operators lifting them.

Easy Access

Because Gorman-Rupp self priming pumps are located at ground level, high and dry above the liquid level, they are easy to access for monitoring, service and repair.

Whereas submersible pumps can only be accessed by opening wet well lids (exposing operators to “working at heights” and “working over water”) and winching or craning pumps to the surface (exposing operators to “working with swinging weights”), operators can access Gorman-Rupp self primers at ground level.

End suction pumps will often need a “dry well” which is accessed by going down stairs or a ladder. They need isolation valves on the suction. This makes them more difficult to access than Gorman-Rupp self primers.

Maintenance Features

Gorman-Rupp 10 Series self priming pumps have been designed to be easy and cost effective to service and maintain. The following features make life easier for operators and very cost effective for asset owners:-

Less Blockages

Because  impellers will handle solids, 10 Series pumps will choke less than most other wastewater/effluent pumps. This minimises downtime, increasing productivity.

Easy Blockage Removal

All pumps will eventually choke on something. But unlike submersible pumps that require cranes, safety barriers and several operators, 10 Series pumps have a large removable cover-plate, allowing access to pump internals in minutes, by just one operator, making blockage removal a quick and easy task.

Easy and Simple Wear Plate Replacement

Wear plates on a Gorman-Rupp 10 Series self priming pumps can be replaced in just a few minutes. Operators just remove the pump inspection cover, and replace the wear plate which is bolted to it via 4 studs. Compare this to some centrifugal and submersible pumps, having wear rings that often require heating the casing ring and/or cooling the wear ring, and often requiring the chiselling off of the old one.

Materials of Construction

Gorman-Rupp pumps can be purchased in a variety of materials of construction, to suit the liquid being pumped.

“Fitted” refers to pumps that are supplied with the standard construction pump, but fitted with special material impeller, wear plate, seal plate and shaft.

“HDI” is Gorman-Rupp’s “Hard Iron”. This material is used to resist the action of abrasive materials such as grit. This material has a Brinell hardness of approximately 400, making it approximately twice as hard as cast iron.

316SS is a marine grade stainless steel, used for service where liquids are corrosive. It has a PREN [Pitting Resistance Equivalent Number] of 27.1 and a Brinell hardness of approximately 217.

CD4MCu is a Duplex Stainless Steel, used where services are corrosive and abrasive. It has a PREN of 32.1 and a hardness of 280-300 on the Brinell scale.

High Chrome impellers, available in Super T Series models T3, T4 and T6 have a brinell hardness of approximately 650 and is an excellent material choice for highly abrasive service.
