Grundfos & Goulds Vertical Multistage Pumps
Vertical multistage (VM) centrifugal pumps deliver high pressure at modest footprints—perfect for clean liquids that need significant TDH. We engineer and supply Grundfos CR/CRE and Goulds (Xylem) e-SV systems for RO/UF, boiler feed, washdown, and pressure boosting.

Quick Selector: Vertical Multistage Lines
| Manufacturer / Technology | Typical Flow | Typical Head / Pressure | Installation | Best For |
|---|---|---|---|---|
| Grundfos CR / CRE (Vertical Multistage Centrifugal) | Up to ~800 GPM (typ.) | Up to ~800+ ft TDH / high pressure | Above grade, inline suction/discharge | RO/UF, boiler feed, wash & CIP, pressure boosting, clean water/chemicals |
| Goulds (Xylem) e-SV (Vertical Multistage Centrifugal) | Up to ~600+ GPM (typ.) | Up to ~700+ ft TDH / high pressure | Above grade, inline suction/discharge | Process water, washdown, HVAC boosting, OEM skids, clean chemicals |
Grundfos CR/CRE vs. Goulds e-SV: Key Differences
Grundfos CR / CRE
- Compact inline VM with wide size range and hydraulic options
- CRE integrates factory VFD and controls for easy automation
- Common materials: 316SS, cast iron (wetted options)
- Excellent choice for RO/UF, boiler feed, boosting, CIP
- Large global install base and service network
Goulds (Xylem) e-SV
- Robust VM platform with stackable stages for higher TDH
- Pairs well with external VFDs and skid packages
- Common materials: 316SS, cast iron options
- Go-to for process water, HVAC boosting, washdown
- Strong OEM integration and standardized footprints
How We Size & Engineer the Correct Vertical Multistage Pump
1) Flow, TDH / Pressure Target, and Curve Position
We place your duty point near the pump’s BEP for efficiency and seal life. Grundfos CR/CRE often covers the widest pressure range; Goulds e-SV offers excellent modular staging for targeted TDH.
2) NPSH & Suction Conditions
Like other above-grade centrifugals, VMs require adequate NPSHa. We review suction piping, temperature, vapor pressure, and elevation to prevent cavitation.
3) Materials & Sealing
Typical constructions: 316SS and cast iron, with seal options from single to compact cartridges. We match elastomers (FKM, EPDM, PTFE) to your SDS.
4) Power, Motors, & Drive
CRE variants include integrated VFDs. We also package external VFDs, soft starters, and control schemes to meet your process demands.

FAQs: Grundfos CR/CRE vs. Goulds e-SV
When should I pick Grundfos CR/CRE vs. Goulds e-SV?
Choose CR/CRE when you want an integrated-drive option or very broad hydraulic coverage. Choose e-SV when you prefer external VFDs, standardized OEM footprints, or specific e-SV stage configurations.
Can vertical multistage pumps run dry?
No. Like other centrifugals, VMs must not run dry. The mechanical seal needs liquid for lubrication and cooling. Use run-dry protection when suction risk exists.
What materials and seals are available?
Common constructions are 316SS and cast iron, with elastomers like FKM, EPDM, PTFE. Seals range from single to compact cartridges; we match the build to your SDS and temperature.
Do you offer integrated VFDs?
Yes—Grundfos CRE integrates a factory VFD and controls. We also supply external VFDs for both CR and e-SV packages with custom control logic.
How fast can you ship?
Many VM builds can ship same day from our CA, WA & AZ hubs. Share your duty point and materials—our engineers will confirm availability and lead time.
