Franklin Electric 1VR Vertical Multistage Pump

The 1VR is a vertical multi-stage centrifugal pump from the Franklin Electric VR Series, used for water supply and pressure boosting, water treatment, light industry, irrigation and agriculture, and HVAC. In-line suction and discharge connections with round flanges keep the installation compact on a small footprint.

All wetted components are 316 stainless steel (N version). The pump end mounts a standard NEMA motor on an oversized thrust bearing, so special high-thrust motors are not required.

• In-line suction and discharge with round ANSI flanges for a compact footprint
• NEMA motor mounting with an oversized thrust bearing in the pump end: no special high-thrust motor needed
• Silicon carbide/graphite/EPDM Type 1 cartridge seal
• Three-phase motors are premium efficiency and inverter-duty rated
• NSF/ANSI 61 and 372 certified

One pump per duty. The 1VR runs at 3,600 RPM; the 1VRL Vertical Multistage Pump uses the same hydraulics at 1,800 RPM for about half the flow and a quarter of the pressure per stage. For duplex to sextuplex pressure boosting on one skid, see the VR SpecPAK booster systems.

Pick the horsepower, then the stage count that gives the pressure you need at your flow. Pressure in the tables is what the pump adds to its inlet pressure; total discharge pressure is inlet pressure plus the table value.

1VR selection by horsepower

Digitized from the published 1VR curves in the Franklin Electric VR Series Catalog Mi9041, p. 8 and p. 10 (vector data), and rounded down; feet of head = PSI × 2.31. Each curve was read on the feet scale and checked against the metric scale of the same chart (within 3%). Franklin prints no head or flow table for the VR Series, so the curve is the source. Curves end at 15-16 GPM by model. The 0 GPM column is the shut-off pressure, the most the pump can add to its inlet pressure. Bold = the last point on that model’s curve. — = beyond the end of that model’s published curve.
