sewage pump

ES 200×200

The Gorman-Rupp ES 200×200 is a low profile packaged sewage pump station with a specially designed fibreglass enclosure that is perfectly adapted to house all of the mechanical and electrical equipment for the complete station. The (two) sewage pumps in the station can either be Gorman-Rupp’s Super T or Ultra V Series sewage pumps. The interior layout of the enclosures is designed to facilitate any service work that needs to be done on the sewape pumps or valves. Flows to 75 l/s for a single pump can be achieved, while the station sits on a footprint of 2.1m x 2.1m. Advantages include:

Lower civil costs/ engineering
Stations are fully equipped and ready to “plug and play”
Lower operational costs
Greatly reduced OH&S issues
Easy access for monitoring or service
Intuitive control system
New advanced level control system keeps electrical equipment out of the wet well
Specially developed acoustic system keeps noise down to a whisper (43 dB(A) at 1.0m)
Available with several different external appearance options
All components within Gorman-Rupp packaged sewage pump stations are warranted for 5 years
Can work with the revolutionary Self Cleaning Sump (SCS) for a complete sustainable system

Lower Civil Costs

With a Gorman-Rupp engineered system, there is great potential to save on civil engineering and site work. Firstly, because the pumps are self priming, only the suction lines are in the wet well, so the sump can be significantly smaller [while delivering the same flow rate capability]. There is also no need to construct a separate valve vault/chamber and assemble all the valves into it as part of the installation procedure, because Gorman-Rupp systems are supplied with all the valves fitted.

The Gorman-Rupp packaged pump stations are pre-tested, completely assembled and ready for installation. Just place them, bolt them down, attach the suction and discharge lines, connect the power, and the job is done.

Fully equipped ES 200 x 200

With Gorman-Rupp packaged sewage pump stations, you only need to connect the piping, hook up the power…. and your station is ready to go.

With a Gorman-Rupp engineered system, there is no need to dig a valve vault, no need to install guide rails or discharge elbows in the wet well, and no need to integrate all of the systems on site when all the equipment arrives in pieces. Your Gorman-Rupp ES 200 x 200 pump station is fully equipped and ready to go. This includes:

Sewage pumps
Pump motors
Isolation valves
Non-return valves
Air release valves
All inter-connecting piping
Suction and discharge gauges to monitor pump performance
Motor control centre
Liquid level control system
Ventilation
Internal lighting
Complete system testing prior to the station leaving Gorman-Rupp
5 Year warranty on everything within the station

Lower Operational Costs

A Gorman-Rupp engineered system will save the asset owner many thousands of dollars [when compared to the submersible pump alternative] over the life of the pump station. The reasons are many:

Access and maintenance are much easier for operators, because the pumps are at ground level and much easier to access.
The pumps themselves are the easiest to maintain in the industry. Just 10 minutes for one operator to adjust internal pump clearances [on both pumps] is just one example of this.
Pumps can be set up with a “self cleaning wet well” so that the contents of the wet well can be removed with every pump cycle [including fat and silt]. This reduces the need for “sucker trucks” to remove silt and fat build-up, because the Gorman-Rupp system can greatly slow down or eliminate this build-up from happening. Solving the problem, not treating the symptom is the answer to this often problematic occurrence.
Very long pump service life when compared to submersible pumps.
No guide rails or discharge bends to ever replace.
No real need to ever open the wet well lids. This means the number of operators needed to attend site for blockage removal or maintenance can be reduced.
Operators can trouble-shoot much easier with pressure gauges than amp readings. Pumps do pressure, not amps. Motor amp readings can be misleading, whereas gauges on the suction and discharge of a self priming pump will tell operators exactly where any issue lies. This cannot be said for amp readings on submersible pumps.
No false call-outs because of pump seal moisture detectors. Self priming pumps don’t have or need them.

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.

Pump Station Controls

Although our Gorman-Rupp packaged pump stations can be supplied “less controls”, we can provide controls that are intuitive and designed specifically for self priming pumps. PLC based controls with simple touch screen interface is combined with pinpoint precision start/stop set points for one or more pumps. Controls can be supplied with DOL starters, soft starters or with VFD’s. Advantages of using Gorman-Rupp designed controls are as follows:

All components in Gorman-Rupp pump stations are warranted for 5 years [including the controls].
The controls are purpose built for self priming pumps.
Controls can incorporate an air bubbler liquid level control, improving reliability and safety.
Touch screen interface is very intuitive and easy to operate.
Locally supported in Australia

Level Control System

Gorman-Rupp engineered systems can be supplied with all of the usual level control systems, but our preference is for the safest and most advanced “air bubbler system”. The principle involves pumping a low volume of air into a tube, which runs down into the wet well. The pressure is accurately measured using a pressure switch. At a fixed density, the hydrostatic pressure remains proportional to the level of water in the wet well. This measurement technology is used anywhere that reliable liquid measurement is required.

The compact compressor/pressure switch device is located in the control panel “high and dry” out of the wet well. Only the air tubing and the air enter the wet well. Advantages include:

No opening wet well lids to access the level control device [like ultrasonics, submersible transducers or floats].
Measurement not affected by surface foam, mist or suspended matter.
Reliable measurement over the long term.
Long compressor life
24V power supply
Quick release connection terminals
Maximum margin for error 0.3%

Sound Attenuation

Gorman-Rupp ES 200 x 200 pump stations can be supplied with an internal acoustic lining to reduce sound emissions to as low as 43 dB(A) at 1 metre. This specification is likely to meet all national, state and local requirements for sound emissions near domestic residences in Australia.

This low rating is achieved from a combination of vibration isolation, sound rated panelling, and applying acoustic surrounds to the ventilation system.

Appearance Options

The ES 200 x 200 has several appearance options to help it blend in with the surrounding environment. The fibreglass can be coloured in any colour from the RAL colour spectrum, but can also be fitted with a brick or stone look facing.
