Grundfos pumps save space in purification systems

Compact sizes and usability made Grundfos MTRE pumps the right choice for Transor Filter GmbH

The company

Transor Filter GmbH has been making durable, self-cleaning micro-filter systems for machine tools for more than 30 years. A "disc filter" design makes Transor’s systems unique. The systems are used for purification and temperature control and are especially useful for grinding and spark erosion.

All Transor systems are modular and can be adapted and expanded for a range of capacities. High-performance pumps and cooling systems are integrated into the systems to optimise energy use. This ensures a reliable, low-maintenance supply of cooling lubricant to the machine tools.

The challenge

Transor Filter GmbH was faced with the challenge of making a compact system that could create high flow levels. For this, the company developed a solution called “TCF,” a space-saving system that had all the options of standard systems but was available in a smaller size.

In developing TCF, Transor engineers made the control cabinet’s size a top priority. The first challenge was to shrink the frequency converter that is used for the pump’s speed control. Variable-speed pumps are particularly indispensable in cooling lubricant supply applications, especially when the system has to supply multiple machines at a constant pressure level or even a single machine at variable pressures.

The solution

Transor solved these issues with Grundfos’ MTRE pumps, which come complete with an MGE motor that can run up to 22 kW. The pump saves space in the control cabinet with a micro-frequency converter that is directly integrated into the motor’s drive unit. In addition, the features provided in the MGE motor enable all the setting options and modes of operation required for machine tools and lubricating coolant supply systems.

"The pump is able to regulate itself completely independently," says technical manager Christian Acker.

These MTRE pumps are used in a "pure" cooling lubricant supply circuit and are responsible for delivering the purified grinding oil to the machine tool.

The benefits

A big benefit of the MTRE is its usability. Multi-level vertical immersion pumps are installed on the cooling lubricant’s supplying tank, with the hydraulics immersed in the pumped fluid.

The pumps are available in numerous sizes and stages and are appropriate for a wide range of flow and pressure levels. By installing empty chambers (compartments without an impeller), it is also possible to adapt the pump’s immersion depth to a variety of tank heights.

External sensors can be installed to help the pumps regulate pressure, differential pressure, temperature, temperature difference or flow rate. The pump automatically adapts its pump capacity to the desired value of the corresponding control parameter in this case.

"The ease of operation and the space-saving arrangement of the motor and micro-frequency converter make these MTRE pumps a good choice for us," says Gerd Hasse, Managing Director of Transor Filter GmbH.

The energy savings (and associated cost savings) possible with e-solution pumps have been winning over more and more Transor customers. This is why the pumps in the MTRE range are also used in cases where there are not size restrictions in the control cabinet.
