Motor Not IncludedThis listing is the pump end only — the hydraulic assembly with its chambers, impellers, shaft and cartridge seal, with no motor. The horsepower and NEMA frame against each part number are a selection rating and a mounting face: they tell you what motor the pump end is built to accept, not what ships with it. Order the motor separately and confirm the frame and coupling against the part number before you buy.
Ships by FreightCRN 5-22 and CRN 5-24 on the 1 1/4 in ANSI 300 lb build and CRN 5-22 and CRN 5-24 on the 1 1/4 in Victaulic build ship on a pallet by LTL freight rather than by parcel carrier. A delivery appointment, a dock or a liftgate may be needed; ask us before ordering if the site has none of those. Only the builds named here ship by freight; every other model and connection in this listing ships by parcel carrier as usual.
Victaulic RatingThe Victaulic grooved coupling is rated PN 50, but the pump end itself is a 25 bar assembly, so the pump rating is the binding limit — design to the pressure in the table above, not to the coupling. Couplings and gaskets are not supplied with the pump end.
What This Is

A CRN pump end is an entire Grundfos vertical multistage hydraulic assembly — pump head, base, chamber stack, impellers, shaft and cartridge shaft seal — supplied without a motor. It is what you order to rebuild an existing CRN installation, to re-stage a pump whose duty has changed, or to build a pump onto a motor you already have.

The pump head, base, chambers, impellers, shaft and sleeves are all AISI 316 stainless steel. The molybdenum in 316 is what resists chloride pitting, and it is the whole reason to choose CRN over CRI. The layout is in-line: suction and discharge sit on the same centreline at the same height, so it drops into a straight pipe run.

This listing covers the CRN 5 frame in 1 1/4 in ANSI 300 lb flanged and 1 1/4 in Victaulic grooved (PJE) connection. Choose the connection with the seal in the variant selector — the two builds differ in port size, pressure rating and shipping weight, and the table below sets them side by side.

1 1/4 in ANSI 300 lb 1 1/4 in ANSI 300 lb 362 psi CRN 5-2 to CRN 5-24 (19) 45–164 lb
1 1/4 in Victaulic 1 1/4 in Victaulic groove, no flange 362 psi CRN 5-2 to CRN 5-24 (19) 36–154 lb

The two builds are not interchangeable in the field: the connection is cast into the pump head and base, so a pump end ordered in the wrong style will not bolt to existing pipework. Match it to what is already installed.

The motor rating and NEMA frame are the motor this pump end is built to accept. No motor is supplied. Stage count is the second number in the model — more stages means more head at the same flow without changing the footprint.

Shaft Seal Options
  • HQQE — silicon-carbide faces, EPDM elastomers, -4 to 248 °F liquid range.
  • HQQV — silicon-carbide faces, FKM (Viton) elastomers, -4 to 194 °F liquid range.

Both are cartridge seals: the seal is replaced as a complete unit without dismantling the pump or setting faces by hand. In the Grundfos code the last letter is the elastomer — E = EPDM, V = FKM (Viton). If you are pumping water, HQQE.

What Is Supplied

Pump end only: pump head, base, chamber stack, impellers, shaft, sleeves and the cartridge shaft seal, factory assembled.

Not included: the motor, the coupling and coupling guard, the motor stool where one is required, controls, starters, drives, base plates, foundation bolts and isolation valves, and the Victaulic couplings and gaskets. If you need a complete pump, order the CRN complete-pump listing instead and we will quote it against the same duty.

Before You OrderConfirm three things: the model and stage count against the duty you need, the motor frame and coupling against the motor you intend to fit, and the connection — the 1 1/4 in ANSI 300 lb or 1 1/4 in Victaulic builds are not interchangeable in the field. Send us the duty point and the existing pump nameplate and we will confirm the part number.

All three documents describe the complete CR pump. A pump end is that same hydraulic assembly without its motor, so the performance curves, dimensions and materials read across — the motor and electrical sections do not apply to what ships.
