SPECIAL FEATURES

Ultra V Series Engine Driven Pump – Special Features

Solids-Handling Impeller

The heavy-duty balanced, two-vane, semi-open ductile iron impellers provide maximum life. Pump-out vanes on the back shroud reduce foreign material build-up behind the impeller, minimising pressure on the seal and maximising bearing life.

Patented Cartridge Seal

Gorman-Rupp’s double floating, self aligning, oil-lubricated mechanical seal is specifically designed for abrasive and/or trash handling applications. The silicon carbide faces and extra large seal oil chamber provide superior dry-run capability. The patented cartridge design also allows for accurate and easy installation.

Replaceable Wear Plate

A replaceable wear plate has Gorman-Rupp’s patent-pending, self-cleaning design to ensure that debris is cleared away and does not collect on the impeller vanes. This innovative design reduces life cycle costs by minimising blockages.

Patented External Shim-less Adjustment System

The shim-less cover plate adjustment allows for accurate maintenance of the clearance between the impeller and wear plate, without realigning belts, couplings or other drive components. Once adjustments have been made, the unique collar and adjusting screw maintains the clearance setting even if the cover plate is removed. Peak efficiency is maintained, while doubling the life of the impeller and wear plate. The life of the wear plate is maximised with the combination of the shim-less cover adjustment and the additional rotating assembly spacers.

Ultra V Series Engine Driven Pump – Overview

Self Priming

Ultra V Series pumps are true self primers. After being filled with liquid, Ultra V Series pumps are guaranteed to prime and (more importantly) re-prime every time. They will do this on suction lifts up to 7.6metres above the liquid level.

Ultra V Series pumps are ideal for continuous, unattended, automatic operation in municipal and 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.

Pump Operator Safety

Duty of Care

It is incumbent upon designers, engineers and asset owners to provide the safest possible environment for operators of pumping equipment. For wastewater pump operators, a danger that is ever present, is that of falling into open wet well pits. Even covered wells need to be opened for pump maintenance as with sewage pump stations. This risk is unavoidable when using submersible pumps, because the pumps are at the bottom of the wastewater wells. When pumps choke or need maintenance, safety lids need to be opened and operators are exposed to falls. This is a serious risk, with potential of serious injury or even death.

This risk can be greatly reduced or even eliminated by using Gorman-Rupp Ultra V Series self priming wastewater pumps, because they can be placed high and dry above the wet well, with no need to ever open wet well lids to expose operators to the risk of falling or drowning.

Reduce Fat Build-Up

One of the issues that plague some wastewater pump installations is that of fat, sediment or debris build-up in wet wells. This has the potential of causing odour issues, regular pump chokes, damage to wet well walls and reduced system reliability. By using a “self-cleaning wet well” design in conjunction with Gorman-Rupp Ultra V series pumps, wet wells have their contents removed (including fat, sediment and other debris) with each and every pump cycle. This removes odour issues, reduces the chances of gas production, reduces the risk of attack to concrete walls, and greatly reduces the need for entry into these wells for the purposes of cleaning etc.

Pump Safety Features

Gorman-Rupp Ultra V Series pumps have more in-built safety features than any other self priming centrifugal pump. A safety pressure relief valve in the pump will vent any excessive pressure build-up. As a back-up to this, the suction check valve has a burst disc that will “pop” if for some reason the pressure relief valve malfunctions [venting any pressure build-up back to the wet well]. Ultra V pumps also have the safest fill port in the industry, by guarding operators against pump contents being sprayed at them when the pump fill port needs to be opened for inspection.

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 Ultra V Series self priming pumps have been designed to be the easiest and most cost effective wastewater pumps to service and maintain. The following features make life easier for operators and very cost effective for asset owners:

Less Blockages

Because all internal passages will handle a 76mm spherical solid on most models, and pumps come standard with a patented self cleaning wear plate system to resist choking from stringy materials such as rags, Ultra V Series pumps will choke much less than most other wastewater 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, Ultra V 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 Clearance Adjustment

Most centrifugal pumps have radial clearances between impeller and wear rings. Gorman-Rupp Ultra V Series pumps have axial clearances that are adjusted through external adjusting screws on the cover-plate. One operator with 2 spanners can adjust clearances in just 4 minutes. Adjusting clearances on some submersible pumps could take several operators most of an entire day.

Easy and Simple Wear Plate Replacement

Wear plates on a Gorman-Rupp Ultra V 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.

Easy Major Overhaul

The major wearing components in a Gorman-Rupp Ultra V, form part of the rotating assembly. This includes the seal, bearings, impeller and seal plate. This “cartridge” is easily replaced on an Ultra V, without needing to take it back to the workshop or even remove the pump from the piping system. Operators simply remove the old rotating assembly by removing 4 bolts, then “plug in” the new one. The old one can then be taken back to the workshop where operators can take their time to replace any worn parts and then use the repaired rotating assembly as a back-up spare.

Replacing Flap Valve

The Ultra V Series range of pumps has the most easily replaced suction flap valve on the market to replace or clean. Just isolate the pump, remove a small cover, then just slip the flap valve out to clean or replace.

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.
