Description
The Grundfos 97652835 (CR 15-3 H-GA-A-V-HQQV) is a Inline multi stage pumps 7.5HP 208-230YY/460YV 3-Phase — Horizontal multistage end-suction pumps. Nominal performance: 79.3US gpm at 156.8ft.
Why This Product
Vertical Multistage Design — High Head at Compact Footprint
Stacked impeller design generates high discharge pressure at moderate flow — the correct performance curve for HVAC pressure boosting, water supply, and industrial applications where single-stage pumps cannot reach required head.
Cartridge Mechanical Seal — Tool-Free Replacement
Pre-set cartridge seal requires no measurement, no adjustment, and no special tools for replacement — just slide in and tighten. The cartridge design also prevents incorrect assembly, which is the most common cause of early seal failure.
In-Line Configuration — No Baseplate Required
Inlet and outlet ports are on the same level, allowing direct inline installation without baseplate, flexible connectors, or special support. Pipe-mounted installation reduces footprint and simplifies installation in mechanical rooms.
All Wetted Parts in Stainless Steel (316 / EN 1.4401)
All components in contact with the pumped fluid are in EN 1.4401 (316) stainless steel — impeller, pump shaft, chamber stacks, top and bottom flanges. No iron contamination in the fluid path. Correct for food-grade, pharmaceutical, and chemical applications.
IE5 Permanent Magnet Motor — Ultra-Premium Efficiency
IE5-rated permanent magnet synchronous motor exceeds even the IE4 "Super Premium" classification. Runs cooler, generates less heat loss, and maintains high efficiency across a wide speed range — important for variable speed applications where the motor rarely runs at full load.

| Electrical | Requires correctly rated supply — 208-230YY/460YV, 3-Phase, 60 Hz. Install with correctly rated circuit protection and motor starter. |
| Temperature limits | Do not exceed max fluid temperature 194°F or max ambient temperature 140°F. Operating outside these limits will damage seals and motor insulation. |
| Dry running | Do not run dry. CR 15-3 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 intervals. Contact PumpStop for documentation. |
