Overview
Installed, aligned and proven against the design duty point.
A pump that runs is not the same as a pump that works. Plenty of installations spin up, make the right noise and deliver considerably less than the design duty — usually because of pipework strain on the flanges, poor suction conditions, incorrect impeller trim, or a commissioning process that consisted of switching it on and listening.
Malanc Projects installs and commissions pump sets across water supply, sanitation, dewatering, fire protection and industrial process duties. We record flow, pressure, current and vibration at commissioning and compare them against the design duty point. If the installation does not reach duty, it is not finished.
Scope of works
What this covers.
Each item is work we self-perform or directly supervise.
- Booster and pressure pump sets
- Multi-pump booster arrangements with duty, assist and standby rotation, correctly controlled to avoid short cycling.
- Borehole and submersible pumps
- Borehole pump installation including rising main, cable, level protection and yield-appropriate selection.
- Sewer and wastewater pumps
- Submersible and dry-well sewer pump installations with guide rail systems, non-return arrangements and confined space procedures.
- Dewatering pump installation
- Temporary and permanent dewatering arrangements for construction and mining applications.
- Fire duty pump sets
- Fire pump sets installed with dedicated supply, changeover and controls appropriate to the fire system requirement.
- Suction and delivery pipework
- Manifolds, headers, valves, strainers and supports arranged so that hydraulic conditions at the pump are actually acceptable.
- Baseplate, grouting and alignment
- Plinth preparation, baseplate setting, grouting and laser or dial alignment recorded on the commissioning sheet.
- Pump control and protection
- Motor control, soft starters and variable speed drives, level control, dry-run protection and duty rotation logic.
- Pump refurbishment and replacement
- Like-for-like replacement, upgrade or refurbishment of existing sets, including adaptation of existing pipework and plinths.
Benefits
Why it matters who does this work.
Verified against duty point
Flow, head, current and vibration measured at commissioning and compared against the design duty — with the results in the handover pack.
Correct alignment and grouting
Baseplates grouted properly and couplings aligned to manufacturer tolerance, with soft-foot checked. This is what determines bearing and seal life.
Pipework that does not strain the pump
Supports and anchors arranged so pipework weight and thermal movement are not transferred into the pump casing.
Controls and protection included
Duty rotation, dry-run protection, level control and motor protection configured to the actual installation, not left on defaults.
Confined space and lifting discipline
Sewer and sump work executed under confined space procedures with gas monitoring and certified lifting arrangements.
Spares and maintenance guidance
Recommended spares, service intervals and failure symptoms explained at handover so the asset can be looked after.
Our process
How we deliver it.
Each stage produces something you can inspect, test or file.
Duty verification
We confirm the required flow and head against the actual system curve rather than accepting a nameplate figure at face value.
Site and pipework survey
Existing plinths, pipework, suction conditions, electrical supply and access recorded and checked for suitability.
Equipment supply or receipt
Pump sets supplied or client-supplied equipment received, inspected and stored correctly before installation.
Installation, grouting and alignment
Set positioned, plinth prepared, baseplate grouted, coupling aligned to tolerance and pipework connected without induced strain.
Sectors
Industries this serves.
The same discipline applied to different operating environments.

Questions
Frequently asked.
We measure it. Flow is established by an appropriate method for the installation, discharge and suction pressures are read, motor current is recorded, and the resulting operating point is compared against the pump curve and the design duty. All of it goes onto the commissioning sheet in the handover pack.
In our experience: pipework strain transferred into the pump casing, misalignment or inadequate grouting, poor suction conditions causing cavitation, short cycling due to badly set controls, and dry running where protection was never configured. Every one of those is an installation and commissioning issue rather than an equipment defect.
Often, yes. We survey the existing plinth, flange positions and pipework, then select or adapt a replacement that fits the existing arrangement. Where the existing arrangement is the reason the old pump failed, we will tell you that and price the correction rather than repeating the problem.
Yes, including the associated dedicated supply, changeover arrangements and control panel. Fire installations carry specific requirements around supply integrity and testing, and the commissioning documentation reflects that.
Yes, where they suit the duty. VSDs are genuinely valuable on variable-demand systems and largely wasted on fixed-duty transfer applications. We will tell you which situation you are in rather than fitting one because it sounds modern.
