Submersible Pumps are suited for tight working areas.
October 25, 2005 -
Designed for continuous operation, Tubo pumps handle pH values from 5-8 and have central discharge suited for use in 8 and 12 in. tubes. Tubo 8 is suited for drainage works in 8 in. filter tubes and other narrow spaces. It has max flow of 307 gpm and pressure head of 177 ft. Also available, Tubo 12 can be used in spaces down to 12 in. and delivers flow up to 903 gpm and pressure head of 262 ft. Built-in air valve enables dry running capabilities without overheating.

Introducing Grindex Tubo
The new submersible Tubo pumps from Grindex are designed for drainage works in narrow spaces. The pumps have a central discharge, allowing them to be used in 8" and 12" tubes. Typical applications include drainage in filter tubes in cohesive soil and dewatering in confined spaces.
The Tubo pump from Grindex is available in two sizes, 8" and 12". Tubo 8 is a completely new pump, developed for drainage works in 8" filter tubes and other narrow spaces. It has a maximum flow of 307 USgpm and a pressure head of 177 ft. Tubo 12 is developed from the well known Proline pumps Minor, Major and Master. The pump has a new designed top and can be used in spaces down to 12". It can deliver a flow up to 903 USgpm and pressure head of 262 ft. Grindex unique built-in air valve enables dry running capabilities without overheating. All Tubo pumps are equipped with thermo switches in the stator windings, allowing the use of an overheating protection system.
- We have seen an increasing demand of the Tubo pumps at construction sites, where the ground water table needs to be lowered temporarily while the foundation work is carried out, says Gunnar Benselfelt, Marketing Manager at Grindex. By lowering the water table locally with a number of Tubo pumps, the concrete works can be done with low impact on the water table surrounding the construction site.
The Tubo pump is also useful for drainage in other narrow spaces, like during pile driving works. When operating in cohesive soil, the pump can be installed in a filter tube that keeps the soil from entering the pump.
To ensure a reliable operation, the Tubo pumps are equipped with double mechanical seals in an oil bath that lubricates and cools the seals. The pumps are designed for continuous operation in demanding environments and can handle pH values from 5 to 8. The impellers are made of chrome-alloyed white cast iron and wear parts made of nitrile rubber for the highest endurance against wear from soil, sand, drill cuttings and alike.
The new Tubo pumps are manufactured mainly from Grindex standard components. Not only does this make servicing faster and easier, it also reduces spare parts inventory.
