Tsurumi has a huge range of submersible pumps, with more than 25 different pump types, this submersible pump specialist has a pump for almost any application, from light domestic usage to heavy duty industrial applications, model dependant Tsurumi submersible pumps can be supplied either free standing or with a guide rail system consequently suitable for fixed or mobile applications, must pump models can be supplied with optional float-switch.

Models available in both single and 3 phase supply, upon request 60 Hz pumps are also available.

Our Tsurumi submersible pumps are available with a variety of impeller types to suit a number of applications and fluids from domestic clean water distribution to industrial sewage, sludge and slurry transfer, depending on the model specified these submersible pumps can handle a max. liquid temperature of 40°C and has a max. solids passage of 100mm.

Tsurumi submersible pumps are available with a variety of different impeller types, sealing options and construction materials.

The Tsurumi PU pump range is a heavy duty submersible pump supplied with a 304 stainless steel motor frame for major corrosion and wear resistance, these pumps are available free-standing or with guide rail systems thus are suitable for both mobile and fixed installations.

The PU pump range is commonly used for light sewage transfer and final effluent, these pumps are supplied with dual hard face mechanical seal (silicon carbide – silicon carbide) and thermoplastic impeller. Available in both single phase 110V / 230V and 400V three phase supply.

FAQS

Can this pump run dry?

No, definitely not! submersible pumps will incur damage even after short periods of dry running. The mechanical seal requires lubrication and cooling while the pump is operating. Without the presence of fluid, the mechanical seal will overheat and crack, and this may cause the pump to leak and fluid to enter the motor. There is also the possibility that the motor will burn out as this requires cooling by the fluid during operation. Our advice is to ensure that the pump and motor are always submerged during operation. There are two main ways to ensure the pump only operates in the event of submersion. Firstly, only the operator turns the pump on and off manually when they have a clear view of the sump. Secondly, fit the pump with a float switch that will automatically turn the pump off once the fluid has dropped to a specific level in the chamber. If you think that dry running is inevitable, then please speak to us and we will try to select a more suitable pump for your application.

What do the terms manual and automatic mean?

Manual and automatic are the two main ways to describe how a submersible pump will operate. Manual means that the operator manually turns the pump on and off when required, turning the pump off and avoiding any possible damage from dry running is solely the liability of the operator. Automatic means that the pump will turn on and off automatically via a float switch or float switches. A float switch is connected to the motor that detects the fluid level in the sump, the pump is turned on when the level is high enough, and the pump is turned off when the fluid drops to an acceptable level.

How do I know what size pump is correct for my application?

A clear picture of the pump system is required to make an accurate selection. The main pieces of information required include; a description of the application, bore of pipework, the fluid, flow rate and pressure/head. With these pieces of information, a pump can be sized correctly to ensure it delivers the required flow rate and pressure and that is also operates at its best efficiency point to lower lifetime costs. Knowing if the pump is running intermittently or continuously also allows the correct motor speed to be selected. For instance, a pump running continuously 24/7 will require a 4 pole motor rather than a 2 pole motor. Running the motor slower and oversizing the pump will reduce wear of the motor and the pump, therefore lowering maintenance costs during their lifetime.

Can the motor really be submerged in water?

Yes, absolutely! In fact, submersible pump motors need to be submerged in fluid during operation for cooling and to avoid overheating. These motors have an IP rating of 68. IP stands for Ingress Protection, this is a measurement of a component's resistance to dust and fluid entering.

What size solids can this pump handle?

Please be aware that the figures displayed relate to the largest pump from this range of products, not specific models. For details on solids passage for specific models, please refer to datasheets or contact a member of our sales team.
