Why This Product

ANSI/NEMA for North American Systems

NBS uses NEMA frame motors and ANSI 150# flanges — the standard for US and Canadian HVAC, water, and industrial systems. Direct replacement for existing ANSI pumps.

Back Pull-Out Design

The rotating element pulls out from the back without disturbing the pump casing or piping. Reduces maintenance downtime to minutes, not hours.

Close-Coupled — No Alignment

Motor and pump share one shaft. No coupling alignment on installation or after service. Reduces vibration and bearing wear.

Wide HP Range

NBS covers 1.5 HP through 75 HP in a single series. One spare impeller kit covers multiple pump sizes in the same installation.

Cast Iron or Stainless Options

Casing and impeller available in cast iron, bronze, or stainless depending on application. Specify material to match your system fluid.

Authorized Distributor — Full Warranty

PumpStop is an authorized Grundfos distributor. All NBS pumps ship with full Grundfos warranty and US technical support.

Important Notices
Electrical Verify supply voltage, phase, and frequency match nameplate before installation: 230/460V, 3.0-Phase, 60 Hz.
Temperature limits Do not exceed max fluid temperature 284°F or max ambient temperature 104°F. Exceeding limits damages seals and motor insulation.
Dry running Do not run dry. NBS 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.
