Submersible Pump · Pumps
A blockage-free screw centrifugal impeller design ensures efficient pumping of raw mixtures containing solid particles, making the Hidrostal F10K-HD a powerful submersible sewage pump. This robust pump features a large waste opening of 120 millimeters and is designed to handle viscous mixtures and contaminated surface water with ease. The pump operates at 400 volts and can pump up to 970 m³ per hour with a maximum pumping height of 30 meters. The electric motor is equipped with an oil cooling jacket, enabling the pump to operate dry, which is especially useful in marine and offshore applications. The pump can be installed vertically or horizontally and includes an external control box for operational flexibility and protection against damage. Widely used in sewage projects, water treatment facilities, and ship salvaging, the F10K-HD is a versatile solution for various pumping needs.

| Seal chamber oil check | every 2,000-4,000 running hours, or annually, whichever comes first |
|---|---|
| Mechanical seal inspection/renewal | typically every 8,000-16,000 running hours depending on duty - confirm against Hidrostal's schedule for the F10K-HD |
| Impeller/wear ring clearance check | annually |
| Insulation resistance test | every 3-6 months for standby-duty pumps |
Typical intervals for this design class, not the manufacturer’s figures for your model. The manufacturer’s manual is binding.
| Impeller/wear ring clearance | typically in the region of 0.3-0.8 mm for a submersible sewage pump of this size class - confirm against Hidrostal's own tolerance table |
|---|---|
| Motor insulation resistance | a commonly used action threshold for wet-duty submersible motors is around 1 MΩ, trending downward over time - confirm against Hidrostal's own criterion |
Ranges are typical for this design class. Always confirm against the manufacturer documentation for your serial number.
Where this pump forms part of a statutory bilge or sewage discharge arrangement, class checks standby pump availability, high-level alarm function, and - if it feeds a sewage treatment discharge - the vessel's MARPOL Annex IV compliance records.
Estimated lifetime: typically 30,000-40,000 running hours to major overhaul for a pump of this size and duty, strongly dependent on solids content and any dry-run incidents - confirm against Hidrostal's service documentation
