A water booster set raises incoming water pressure to reliably feed a building, process or system. Where mains pressure is too low, or where demand fluctuates more than the mains alone can handle, a booster set delivers the consistent flow and pressure the site needs.
At TF Pumps we supply pre-fabricated booster sets from all the leading European manufacturers, along with fully bespoke booster sets engineered to your exact specification. From compact domestic units to triplex sets feeding high-rise apartment blocks, we specify, supply and support the right solution.

A booster set, sometimes called a pressure booster set or water booster set, is a packaged pumping system that takes a water supply at one pressure and delivers it at a higher, controlled pressure. A typical set contains one or more centrifugal pumps mounted on a common base, a control panel managing pump start/stop and sequencing, pressure sensors, a pressure vessel to absorb demand fluctuations, and the valves and pipework that tie everything together.
Modern booster sets almost always run on variable speed drives (VSDs). Rather than simply switching pumps on and off against a pressure switch, the VSD modulates motor speed to match demand precisely. As a result, the system maintains constant outlet pressure regardless of flow, consumes less energy, and experiences significantly less mechanical wear.
Single-pump sets offer the simplest configuration, suited to small commercial units, domestic properties and light-duty applications where there is no standby requirement.
Twin-pump (duty/standby) sets represent the most common configuration in commercial buildings. Two identical pumps share the duty on an alternating basis; if one fails, the other carries the full load automatically. This arrangement strikes the right balance between reliability and cost for most commercial and light industrial sites.
Triple-pump and multi-pump sets suit sites with large or highly variable demand, such as hotels, hospitals, high-rise residential and large industrial plants. These systems split duty across pumps, with one modulating on VSD to hold pressure and additional pumps starting on demand.
Variable-speed vs fixed-speed: for any site with variable demand, which covers almost all applications, VSD is the right choice. However, we still supply fixed-speed sets where the application genuinely suits them.
Manufacturers like Lowara and Ebara build pre-fabricated booster sets to standard configurations. Because these units leave the factory fully tested, they offer competitive pricing and short lead times. If your duty point fits a standard range, a pre-fabricated booster set is almost always the quickest and most cost-effective answer. In many cases, common models sit on the shelf and can ship within days.
In contrast, bespoke booster sets start from scratch, engineered to a project’s specific duty, footprint, control philosophy and materials specification. You should consider this route where you need unusual flow and head combinations, stainless-steel construction for hygienic applications, BMS integration, or anything a catalogue unit cannot deliver. A packaged booster set built to order typically takes six to twelve weeks, but the system matches the job precisely.
Many projects sit on the boundary between the two. We help clients decide which side of the line their requirement falls on and then deliver either option.
Correct sizing is the single biggest factor in how well a booster pump set performs over its lifetime. The calculation depends on peak flow rate (number and type of outlets with appropriate diversity factors), total head required (static lift plus friction losses plus residual outlet pressure), the pressure the mains already provides, and duty pattern.
As independent suppliers, we stock booster sets from leading European manufacturers including Lowara, Ebara and Calpeda, so the recommendation you receive matches the right equipment to the application rather than defaulting to a single brand. Call us on +44 1332 913500 to discuss your project.

Sizing depends on peak flow demand, the total head the pumps need to overcome, and the incoming mains pressure. For example, a typical two-bed flat in a new development might need a small twin set delivering 2-3 l/s at 4-5 bar. In contrast, a ten-storey residential block might require 8-12 l/s at 8 bar or higher. Simply send us your project details and we will specify the right set.
A booster pump is a single piece of equipment, one pump on its own. A booster set, on the other hand, is an engineered package: multiple pumps on a common base with a control panel, pressure vessel, pipework and valves, all built to work together as a system. In other words, a booster set is what you install in a building, while a booster pump is the component inside it.
A well-specified, correctly installed and maintained commercial booster set typically delivers 15-20 years of service. However, pumps and motors have a shorter life than the overall package, so you should expect to replace or refurbish the pump ends at around the 10-year point.
Modern VSD-controlled booster sets are quiet in normal operation typically 55–65 dB at 1 metre, comparable to an office air-handling unit. Noise issues are almost always caused by cavitation (insufficient inlet pressure), resonance in pipework, or sets mounted directly onto structural floors without anti-vibration mounts. All of these are straightforward to design out.
Yes, with suitable weatherproofing. Many booster sets sit in plant rooms, but outdoor installation is common on industrial and agricultural sites. For an outdoor setup, you will typically need an IP-rated control panel, frost protection and a weatherproof enclosure.
