What is the maximum head/flow of the Grundfos CR 20-2?

The CR 20-2 produces approximately 190 ft of head at 115 GPM (best efficiency point), with a shutoff head of about 228 ft. That corresponds to roughly 82 psi at the BEP.

What is the Grundfos CR 20-2 material number / part number?

The primary material number for this configuration (3-phase 208-230/460, HQQE seal) is 99917735. Other voltage and seal options are listed in the variants table on this page.

Which motor does the Grundfos CR 20-2 use?

This SKU ships with a 5 HP, 3-phase, 208-230/460 V NEMA TEFC motor on a 182TC frame. Other motor configurations and IE3/IE5 upgrades are available on request.

Can the Grundfos CR 20-2 be paired with a variable frequency drive (VFD)?

Yes. Order the matching E-Pump variant with integrated MLE permanent-magnet motor, or pair this fixed-speed pump with a Grundfos CUE external VFD.

Many configurations of the CR 20 series ship from stock through Grundfos USA. Contact ForeverPure Place for the current lead time on this specific material number (99917735).

Grundfos CR 20-2 5HP 3PH Pump | P/N 99917735

Description

Grundfos CR 20-2 — material number 99917735 — is a 2-stage Grundfos CR vertical multistage centrifugal pump with a 5 HP, 3-phase, 208-230/460 V NEMA TEFC motor and a HQQE shaft seal.

This 2-stage configuration produces a moderate 190 ft of head at the BEP (115 GPM, ~82 psi) and is the most common choice for low-rise commercial boosting and short pipe runs where modest pressure is needed.
