COMPACT TANK TOP _ SOLUTIONS FOR DEMANDING APPLICATIONS think innovate

RENOWNED FOR THEIR RELIABILITY AND PRECISION When you choose a Grundfos immersible pump, you get a pump used by the metal processing industry for decades that has proven its worth. In addition, the Grundfos range of MTR, MTH, MTA and MTS immersible pumps include sizes and material variants that fit general industry applications, bringing their renowned reliability and precision to an even wider number of application areas. A Grundfos immersible pumping solution will optimise your processes, increase efficiency, and lower your energy consumption. All pumps are available for 50 Hz or 60 Hz operation...

The MTR, MTH and MTA vertical multistage centrifugal pumps and the MTS screw pumps are designed for mounting on top of tanks with the pump unit immersed in the liquid to be pumped. The pumps consist of two main components: The motor and the pump unit. Depending on the solution required, the length of the immersed pump unit can vary. With a range capable of delivering from 0.5 to 102 m3/h at pressures of up to 150 bar where required, there is a Grundfos immersible pump for every process. Applications where Grundfos immersible pumps are used include: • Machine tool Delivers the pressure and flow...

The MTR RANGE – where power is required The MTR range offers a broad range of high efficiency pumps of different immersible length for varying flow and pressure requirements of up to 102 m³/h (1700 l/min) and pressures up to 35 bar. MTR pumps are available as a customised solution in cast iron or stainless steel and in number of variants. In addition to machine tool, wash & clean applications, and the circulation of cooling liquids, MTR pumps are also used as condensate or filter pumps. They are well suited for water treatment applications as well. MOTOR Standard IE3 motor (MTR) and with an integrated...

APPROVALS Meets current motor and pump efficiency requirements applicable in your market such as the global MEPS (Minimum Energy Performance Standards) for the motor and the Ecodesign requirements for rotodynamic water pumps defined by the Minimum Efficiency Index (MEI). Available in three material variants - cast iron and two different stainless steel grades, covering everything from clean water, coolant to chemical applications Flow rate: max 102 m3/h (1700 l/min) Grundfos offers a wide range of balanced cartridge shaft seals with different seal faces such as Silicon Carbide, Carbon and...

The MTR RANGE – available in the following variants The MTR range offers a high degree of modularity using standard motors and a range of variants for specific applications. MTR – DRAINAGE BACK TO TANK Leak-free pumps are a top priority in any industrial process. Leaking pumps may lead to costly downtime and in turn affect part cost. The MTR DBT (Drainage Back to Tank) pump effectively eliminates that risk, as the liquid remains in the tank where it is supposed to be – even if the shaft seal is worn out and starts to leak. In addition to being leak-free, the MTR DBT pump features an innovative...

In certain applications you need to increase pressure as you wish. Customised software allows the pump's RPM to be practically doubled, and the increased speed - referred to as over-synchronous operation - translates into greatly increased pressure and means you get the high pressure you need from a significantly smaller pump. This can be achieved because the pump does not need to perform across the full pump curve. Instead, the software lets the pump operate only within the necessary band with perfect precision. Maximum performance when operating at power limit Maximum power curve when operating...

The MTH RANGE – with integrated motor The MTH range of immersible pumps with the motor and pump in one unit is very compact, increasing the ease of installation. Available in cast iron or stainless steel, the MTH range can be supplied in different immersible lengths for varying flow and pressure requirements. The MTH pump comes with dual frequency 50/60 Hz as standard. The MTH range is ideal for machine tool, wash & clean and chiller applications. Pump capabilities: Flow rate: Liquid temp.: Pump sizes: • Motor Standard IE3 motor available for global voltage with rs. single and three-phase motors....

The MTA RANGE – for filtering systems The MTA range of single-stage immersible pumps has been designed especially for filtering systems in the machine tool industry. The semi-open impellers allow the passing of chips up to 10 mm, making the pumps ideal for removing liquid from any machining process – from boring and milling to grinding. The compact MTA pumps efficiently transport liquid containing chips, fibres and abrasive particles on to the filtering unit. The low-pressure pumps are available in many different flow variants and come with a choice of bottom suction or suction from the top of...

The MTS RANGE – high pressure screw pumps Grundfos MTS pumps are screw pumps designed for high pressure pumping of cooling lubricants and cutting oils for machine tool applications. These pumps come with various pump sizes and screw pitches to provide the flow and pressure required. Using MTS screw pumps in machine tool applications, where high pressure is required, results in an increased surface quality and a decreased machining time. The MTS pump is available in different installation variants, such as tank top, in-tank and dry installation, all with a range of connection options. Pump capabilities:...

HIGH EFFICIENCY MOTORS In addition to our standard motors, Grundfos can supply motors that meet special supply voltages, extreme operating conditions, special motor protection, specific approvals and special motor design. • ATEX approved A full range of special explosion-proof and dust ignition-proof motors is available with ATEX-approved pumps • Standard MGE motors The Grundfos MGE motor with integrated frequency converter can operate at different speeds to optimise pump performance for applications ranging from low speed to over-synchronous speed. Motor protection, pump monitoring, and onboard...
