Description
The Grundfos 96520256 (MTR 20-5/5 A-WB-I-HUUV) is a Submersible Multistage Pump — Tank Top. Vertical multistage pump for tank top mounting. For machine tool coolant, deionized water, and process liquid applications. Nominal performance: 111US gpm at 268.7ft. Rated 208-230/460V, 3-Phase, 60 Hz. Applications include Machining.
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.

| Temperature limits | Do not exceed max fluid temperature 194°F or max ambient temperature 104°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. |
