Single-stage performance curve
GEOTHERMAL / CONSTRUCTION OPTIONS
The materials inside the pump.
Stage assembly and material options allow the configuration to reflect the fluid and mechanical requirements of the well.
| Component | Catalogue construction / options |
|---|---|
| Radial bearings | VK8-V hard alloy |
| Stages | Ni-resist cast iron; stainless powder-alloy option |
| Shaft | High-strength corrosion-resistant steel; Alloy 925 (718) options |
| End parts | Structural steel; stainless steel for corrosion-resistant versions |
| Fasteners | Structural alloy steel; K-Monel options |
| Corrosion-resistant housings | Metallic protective coating |
TP and QJ construction
TP diffusers are assembled inside a housing. QJ uses bolted diffusers without a continuous outer housing.
Stage-assembly codes
FLT identifies floater construction; PKT identifies packet construction; CPM identifies compression construction.
| Code | Meaning |
|---|---|
| AR1 | Abrasion-resistant configuration: solids up to 500 mg/L |
| AR2 | Abrasion-resistant configuration: solids up to 1,000 mg/L |
| CR | Corrosion-resistant configuration |
OILFIELD PUMPS
362, 400 and 512 series.
Modular centrifugal pumps for formation-fluid production. The catalogue portfolio spans approximately 315–3,144 BPD and provides floater and packet stage-assembly options.

| 362 | 92 mm / 3.62 in | Modular centrifugal pump |
| 400 | 103 mm / 4.06 in | Modular centrifugal pump |
| 512 | 130 mm / 5.12 in | Modular centrifugal pump |
| Code | Meaning |
|---|---|
| FLT | Floater stage assembly |
| PKT | Packet stage assembly |
| S11–S14 | Stainless-steel shaft options, 1,080–1,370 MPa yield point |
| M11–M14 | Alloy 925 (718) shaft options, 1,080–1,370 MPa yield point |
| CR | Corrosion-resistant housing configuration |
PERFORMANCE CURVES
Get the curve for your operating point.
Oilfield performance curves are supplied for the selected pump model and speed. Include flow, required head and fluid conditions so the head, power and efficiency curves can be matched to your application.
Catalogue values are reference data. Final series, stage count, materials and operating range are confirmed against the actual well conditions.
