Pump FAQs

A drainage pump transports water, sewerage or liquids from one location to another. Drainage pumps typically use layflat hose and suction-delivery hose attached to the pump inlet and outlet to transport the water. Some variations have permanently installed pipework to move the liquid from one location to another. Drainage pumps can be used in many applications including domestic, industrial, agricultural, quarries, sewage treatment works and for general water extraction.

Drainage pump installation should be done by a suitably mechanically trained person, T-T Pumps has engineer teams that can install equipment if required.

Many drainage pumps have a strainer base due to a low tolerance for solids passing through the pump, the most important thing is to keep this clear to allow sufficient water into the pump for normal operation.

Not necessarily, grinder systems are suitable when a small diameter rising main must be used or there is a high head to overcome. Also, consider a vortex style pump for sewage which is capable of handling solid waste by breaking it down. Contact T-T Sales Department for guidance

No pump is designed to handle tampons, and stopping them from entering the pump through educating the users of a system and or screening the sewage reaching the pump is best. This being said most sewage pumps are "free passage" types. This means that they allow solids through the pump into the pipework, so if the free passage if large enough it should pass a tampon.

Our sewage pumps commonly are 70dB at a 1m distance, although this depends on the offered pump.

A correctly sized sewage pump should run reliably if the system is not abused. At T-T Pumps we offer bespoke sizings of pumps to offer pumps suited to the application and we are the sole distributor for Zenit pumps in the UK and Ireland who have been producing reliable sewage pumps for many years.

The most commonly used sewage pumps are free passage types that allow solids to pass through the pump whilst using centrifugal force to move the sewage.

Normally an venturi attachment is fitted to a sewage pump to allow the pump to offer some aeration. T-T Pumps can offer bespoke sizing of sewage ejector pumps or aerators.

If a sewage pump is going to be used in a basement there will need to be some way to collect the sewage and contain the smell of the sewage such as the Trojan range from T-T Pumps, as these are above ground packaged pump stations. We also offer a range of below-ground basement pumps, these are our Pluto range.

The most commonly used submersible sewage pumps are free passage types that allow solids to pass through the pump whilst using centrifugal force to move the sewage.

There is no set period of time a sewage pump will last for, although a properly selected and maintained pump will often long outlast the manufacturer's warranty period. We can help with pump selections and servicing through our sales and service departments so please contact us by email or phone.

Yes, sewage pumps can be sized and selected to ensure the liquid is transerred at the appropriate distance and head for the application.

Yes, a submersible sewage pump can be used in a sump application. The typical difference between a sewage pump and sump pump is the solids handling. Typically a sewage pump is required to handle larger solid particles whereas a sump pump or drainage pump is used for pumping clear waters. Although all submersible pumps can be used in a sump, they just need to be sized correctly, with the correct starting equipment to fit in the size of the sump.

A sewage pump transports sewerage liquids and solids from one location to another. They are typically used when sewerage can not be moved via gravity. If the sewerage is lower than the sewer and sewage pump is used to move the liquid to the sewer. Sewage pumps usually have a vortex, channel or chopper impeller, these impellers are suitable for handling the solid content present in the sewerage.

Sewage pumps are centrifugal pumps, meaning they contain a motor which spins the impeller.
The rotating impeller creates a suction that lifts the liquid into the pump and through out the discharge. Sewage pumps need to have a suitable impeller to allow the solid particles to pass through the pump body.

Attach hose and secure to the discharge connection, lay hose appropriately to where you would like the discharge water to be removed to. Connect to a power source, this should be done by a competent electricially qualified person. For automatic operation combine with the PumpPal control unit and LevelPal. The LevelPal is a level detection unit which will communicate to the PumpPal when to turn the pump on and off.

By using a special seal in the base of the pump, puddle pumps can pump to a low level (1mm) using centrifugal force to pump water away and can be automated with accessories, we offer the PuddlePal pump with the LevelPal and PumpPal.

A type of pump designed to pump low-levels of water due to the pump being fitted with a special seal and volute in the bottom of the unit which enables the low-level pumping. These can be as automatic puddle pumps or puddle pumps with a float switch.

The size of an irrigation pump will depend on what it is irrigating as well as the nozzles being used and the pipework arrangement. 

A pump to supply water for irrigation purposes i.e. to water crops or grass.

The best irrigation pump is a reliable and energy efficient pump that can provide the duty needed for the required application.

It is best for the unit and attached system to be inspected by a suitably mechanically trained person. Although this depends on the pump being used as an irrigation pump as some pumps used for irrigation do not require priming.

If the irrigation pump is supposed to operate automatically with a controls system it is best that someone suitably electrically trained inspect the pump and controls, which T-T Controls can help with.

Whether the irrigation pump is manually or automatically operated, it is best that someone suitably electrically trained inspect the pump (and controls if appropriate), which T-T Controls can help with.

The main cause for a drop in pressure is a leak in the system or the pressure vessel has failed, causing a drop in pressure of the system.

We at T-T Pumps sell irrigation pumps as well as offering bespoke sizings for the pumps and accompanying control systems as required.

Normally an irrigation pump will be installed near the water supply or water tank that is feeding the system and then pump the water to where the irrigation is required.

Replacing a pump motor should be done by a suitablly mechanically and electrically trained person. T-T Pumps have travelling site engineers as well as a workshop at our site that can help with this.

Our T-T Controls department can create bespoke controls for an irrigation system to match your desired operation for the system. One (simple) example would be a timer that runs the system at specified times.

Connect the irrigation pump to a water supply and electrical supply then have it pump water to the desired crops or grass etc.

Speak to a competant electrically and mechanically trained engineer, you can call or email T-T Pumps for help with pump related enquiries.

Check the O&M manual for the pump and check what temperature range the pump can work in. If the pump needs protection from low temperatures take care that it still has sufficient cooling for the motor to run without overheating.

A variety of pump types can be used as irrigation pumps, not all of which will hold water however to drain the pump and pipework any non-return valves will need to be opened or removed.

Once the pumps are installed and commissioned the pipework system must be sealed and then the pumps are turned on in order to provide the pressurization within the system. This should be done by a suitablly mechanically trained person, T-T Pumps has travelling site enineers who can help with pressurizing systems.

Competant electrically trained engineers should connect the unit, T-T Pumps have travelling site engineers as well as a workshop at our site that can help with this.

If you contact T-T Pumps with the details of your application and / or the name of your current pump model we can size a replacement unit for you. Please note it is best practice to size from application details.

The size of an irrigation pump will depend on what it is irrigating as well as the nozzles being used and pipework arrangement. T-T Pumps can do bespoke sizings for irrigation pumps if provided with the details of the application.

The pump supplies water for irrigation purposes i.e. to water crops or grass, the pumps we supply at T-T Pumps typically use centrifugal force to achieve this.

A pump that is powered by a petrol or diesel engine.

The pumping action operates as normal, we offer centrifugal and diaphragm engine pumps. The unit is powered by a petrol or diesel engine instead of an electric motor which is commonly used.

There is no set period of time a well pump will last for, although a properly selected and maintained pump will often long outlast the manufacturer's warranty period. We can help with pump selections and servicing through our sales and service departments so please contact us by email or phone.

The best well pump is a reliable and energy efficient unit that provides the required duty. Our sales department can do bespoke sizings of well pumps so please contact us by phone or email.

A submersible propeller creates a current in the liquid in order to mix it.

A suitably mechanically trained engineer should connect the pump to the discharge pipework and if required the suction pipework.

A washdown pump works by discharging water, at a higher pressure and flow than the mains water supply to enable washdown.

The pump should be mounted to ensure adequate water supply whether it is a surface mounted or submersible pump.

A suitably electrically trained engineer should wire the connection.

Ensure the unit is housed in a container, potentially with a heater, in order to prevent the temperature of the pump dropping below the minimum.

The pump should be installed by a suitably mechanically and electrically trained engineer.

The best washdown pump is one that provides high flow and reasonable pressure in the system it is installed in, whilst preferably being energy efficient.
