Reading the model code
ES 50/20: 50 is the discharge nozzle (DN50) and 20 the nominal impeller diameter in cm. The suction is one size larger than the discharge (DN65 here). MS means mechanical seal, GP gland packing.
Mechanical seal or gland packing?
| Option | Best for |
|---|---|
| Mechanical seal (MS) | Clean water, no leakage, low maintenance |
| Gland packing (GP) | Water with some solids, easy site maintenance; a small controlled drip is normal |

Prices are for bareshaft pumps only. Motor and build-up prices are on request, and trimming and balancing of impellers is charged extra.
Selecting an ES pump
- Work out the flow and the total head (static + friction + pressure).
- Choose the series by flow — the discharge size limits flow.
- Choose the impeller size whose curve meets your duty near its best efficiency point; the ES datasheets on each category page show the curves.
- Choose the seal type and ask us to quote the motor and base plate.
Frequently asked questions
What does ES 65/26 mean?
Discharge DN65, nominal impeller diameter 26 cm, suction DN80.
Is a motor included?
No. ES pumps are sold bareshaft; we quote motors and complete build-ups on request.
Is the ES self-priming?
No. It needs a flooded suction or a foot valve and a primed suction line.
Need an end-suction pump built up?
Send us the flow, head, liquid and supply voltage; we will quote the pump, motor and base plate.
