Published fields to check.
These are selected catalogue fields from the source below. They do not establish availability, an accepted specification or compatibility with your machine.
| Field | Supplier-listed value |
|---|---|
| Listed stroke | 100 mm |
| Listed liner diameters | 80 mm / 65 mm |
| Listed input power / input speed | 15 kW / 500 r/min |
| Listed suction / discharge hose inside diameter | 76 mm / 51 mm |
| Listed dimensions / weight | 1100 × 995 × 650 mm / 760 kg |
What still needs confirmation?
The first four duty rows belong to the 80 mm liner group and the next four to the 65 mm group in the supplier table. The source also uses a generic low-pressure label; use the numerical duty rows for the enquiry. The 250 L/min and 7 MPa endpoints are different settings, not one promised operating point. Confirm whether the listed size / weight covers the bare pump or a complete driven set.
Keep each duty setting together.
Each row is a separate supplier-listed setting. Flow is in litres per minute; pressure is in MPa. Confirm the applicable liner, drive and operating conditions.
| Pump speed (strokes/min) | Flow (L/min) | Discharge pressure (MPa) |
|---|---|---|
| 200 | 250 | 2.5 |
| 116 | 145 | 4.5 |
| 74 | 90 | 6 |
| 42 | 52 | 6 |
| 200 | 166 | 4 |
