Sewage Submersible Pumps for STP and Wastewater Transfer

Rinku Engineers is a sewage submersible pump manufacturer and supplier in Ahmedabad, Gujarat. Our AYUSH ASSP Series is designed for submerged sewage and wastewater transfer. Share your required flow, pumping head and wastewater details so we can help you select a pump for your site.

A sewage collection pit needs a pump that matches both the liquid and the pipe system. A pump chosen only by horsepower may deliver too little flow, face repeated blockages or use more power than the application needs. Selection should start with the operating duty and the waste the pump must handle.

We supply sewage pumping solutions for projects in Ahmedabad, across Gujarat and throughout India. Contact our Vatva GIDC office for model selection, application discussions and a quotation with a clear scope of supply.

What Is a Sewage Submersible Pump?

A sewage submersible pump moves wastewater containing suspended solids while the pump and motor operate below the liquid surface. It is commonly installed in a sewage pit, collection tank or wet well to transfer wastewater to a sewer line or treatment system.

The electric motor drives an impeller, which moves the liquid through the pump casing and discharge pipe. A suitable solids passage and impeller design help the pump handle the waste expected at the site. The permitted solid size, liquid temperature and operating conditions must match the selected model.

“Submersible” describes how a pump is installed. “Sewage” describes the liquid it handles. A clean water submersible pump and a sewage submersible pump therefore serve different duties, even though both can operate underwater.

AYUSH ASSP Series Sewage Submersible Pumps

The AYUSH ASSP Series is Rinku Engineers’ sewage submersible pump range. It is intended for wastewater duties where the pump operates inside the collection pit. Selecting the right ASSP configuration requires a review of the wastewater, required output and installation arrangement.

For an ASSP enquiry, discuss:

  • The impeller design and solids passage needed for your wastewater.
  • Pump casing, shaft and seal materials suitable for the liquid.
  • Motor rating, electrical supply and expected running hours.
  • The liquid level required for motor cooling and pump operation.
  • Discharge connection, cable length and access for servicing.

View the AYUSH ASSP Series product page for the product range, and request the current datasheet and performance curve for the proposed model.

Where Are Sewage Submersible Pumps Used?

Application Pumping requirement Selection detail to check
Sewage treatment plants Transfer collected sewage between system stages Peak flow, solids passage and running duty
Housing societies and commercial buildings Lift wastewater where gravity drainage is insufficient Inflow variation, pit level control and discharge head
Hotels and restaurants Transfer wastewater from collection pits Fibrous waste, grease conditions and pretreatment needs
Industrial wastewater collection Move wastewater towards a treatment system Chemical compatibility, temperature and abrasive content
Basement drainage and construction pits Remove collected dirty water Sand content, expected solids and suitability for the duty

Industrial effluent and abrasive slurry need a separate application review. A pump suitable for domestic sewage may not be suitable for concentrated chemicals or heavy sand loads. Share the liquid details before finalising materials and pump construction.

How to Choose the Right Sewage Submersible Pump

Start with Required Flow and Total Dynamic Head

Flow is the volume of wastewater the pump must move over time. Specify it in litres per minute or cubic metres per hour. Include peak inflow and the required pumping cycle when discussing capacity.

Total dynamic head includes the elevation difference, pipe friction and losses through valves and fittings. Any pressure difference between the collection and discharge points must also be included. The vertical lift alone does not describe the full pumping requirement.

For example, an open tank system with a 6 metre static lift and 4 metres of estimated pipe and fitting losses needs about 10 metres of head at the required flow. This is an illustrative calculation. The actual duty must be checked against the selected pump’s performance curve.

Check Solids and Fibrous Waste

Tell the supplier about the largest expected solids and the presence of cloth, fibres, grit or grease. A non clog design helps pass suitable waste, but it does not make every material safe to pump. Solids passage is a model specification and should be confirmed in millimetres.

If cutting or grinding is needed, discuss a pump specifically designed for that duty. Do not assume that every sewage submersible pump includes a cutter.

Match Materials and Electrical Supply

Provide the liquid temperature and any chemical content that could affect the casing, impeller, seals or cable. For industrial effluent, include pH and known chemicals where available. Material choice should follow compatibility with the actual wastewater.

Confirm the site voltage, phase, frequency and available control arrangement. Motor power should follow the selected hydraulic duty and pump curve rather than being the only basis for purchase.

Technical Details to Confirm Before Ordering

Ask for a model specific datasheet with the quotation. A range maximum for flow or head does not mean that one pump delivers both maximum values at the same time.

Selection detail Information to specify or request
Required duty Flow at the calculated total dynamic head
Solids passage Maximum permitted solid size and waste characteristics
Motor kW or HP, voltage, phase, frequency and duty rating
Pump construction Casing, impeller, shaft and seal materials
Liquid limits Approved temperature and chemical conditions
Installation Pit dimensions, immersion limits and servicing access
Connection and cable Discharge size, cable specification and cable length
Performance evidence Pump curve and available test documentation

Installation and Automatic Operation

Plan the installation so the pump can be inspected and removed for service. Check pit dimensions, the discharge route and the minimum operating liquid level before ordering. A permanent installation may use guide rails and an auto coupling arrangement where the selected model supports them.

Level controls can start and stop the pump as wastewater rises and falls. Discuss low level protection, motor protection and a high level alarm with the installation team. Sites that need backup capacity should also review a duty and standby arrangement.

Confirm which controls and accessories are included in the quotation. Follow the manufacturer’s installation instructions for the selected pump. A sewage submersible pump should never be lifted by its electrical cable.
