Why This Product

Tank Top Installation

MTR installs directly on the tank lid — no pipe supports, no baseplate, no inline piping modifications. Ready to run in the space the tank already occupies.

Stainless Steel Throughout

All wetted parts in stainless steel. No corrosion from coolants, deionized water, cutting fluids, or mild process chemicals.

Multistage for High Head in Small Diameter

Multiple stages in a 4" or 6" diameter column provide the head of a much larger pump. Ideal where vertical space exists but floor space is limited.

Wide Flow and Head Range

MTR series covers 0.5 to 16 m³/h flow and up to 235 m head. Confirms correct model for your system requirements.

MTRE Variable Speed Option

MTRE adds an integrated frequency converter for constant pressure control. Same tank top installation, no external VFD required.

Genuine Grundfos Parts Available

As an authorized Grundfos distributor, PumpStop stocks and can source MTR repair kits, mechanical seals, and service components.

Important Notices
Electrical Verify supply voltage, phase, and frequency match nameplate before installation: 208-230YY/460YV, 3.0-Phase, 60 Hz.
Temperature limits Do not exceed max fluid temperature 194°F or max ambient temperature 140°F. Exceeding limits damages seals and motor insulation.
Dry running Do not run dry. MTR pumps use the pumped fluid to lubricate the shaft seal. Dry running destroys the seal within seconds. Install dry-run protection on all automatic installations.
Maintenance Refer to the Grundfos Installation and Operating Manual (IOM) for correct installation, commissioning, and maintenance. Contact PumpStop for documentation.
