Packaged pump stations are complete, ready-to-install systems that combine a chamber, submersible pump, internal pipework, non-return valve, and float switch in a single unit. Once installed below ground, they operate automatically with minimal intervention.
Our range covers clean water, grey water, foul water, and high-flow flood applications, with both single and twin pump configurations.
If you are looking for a standalone pump rather than a complete system, see our Submersible Pumps collection.
Cross-section of a sealed MDPE sump with an automatic submersible pump and arm float switch. Watch one full cycle below.
Rainwater or seepage flows in via the gravity inlet and pools at the bottom of the buried chamber.
As the level climbs, the arm float lifts. At the trigger height it closes the switch contact.
The Ama-Drainer N 301 powers up, lifting water through the riser and out to the sewer.
The arm drops as water clears. The switch opens and the pump rests until the next cycle.
Foul or surface water collected from the gravity inlet at the side of the chamber.
Submersible Ama-Drainer N 301, switched by the float arm.
Arm float switch closes the circuit at the high-water mark and opens at cut-out.
Robust MDPE shell with flanged base to anchor against buoyancy and ground movement.
Every station below is a complete unit: a 190 litre chamber supplied with the pump, internal pipework, non-return valve and float switch. The right one comes down to the water you are moving and the flow and head you need.
| System | Flow rate (L/min) | Head (m) | Best for |
|---|---|---|---|
| Iguazu Sump 635 (single) | 166 | 6.5 | Basement waterproofing, grey, clean and flood water |
| Iguazu Sump Twin | 2 x 166 | 6.5 | Basement waterproofing, grey, clean and flood water |
| Iguazu Sump Foul (Hippo 50) | 330 | 7 | Foul water, sewage, grey water and flood water |
| Iguazu Sump FEKA (stainless) | 400 | 7.5 | Foul, sewage and grey water where a stainless pump is preferred |
| Iguazu Sump Foul Pro (Hippo 100) | 480 | 11 | Foul, sewage and grey water on longer or higher discharge runs |
| Microforce (APP HD-15A) | 830 | 10 | Large-scale flood water, high-inflow sites |
The same units can have a number of use cases. These are the jobs our 190 litre stations do most often.
The first decision is the type of water, because it sets the pump you need.
Clean water is rainwater, groundwater and surface water. Grey water is waste from sinks, showers and washing machines. Foul water contains sewage and needs a pump rated to pass solids.
Where waste cannot reach the sewer by gravity, for example from a basement, an extension below sewer level or a low-lying site, a foul water pump station lifts it to the connection point. Our Sump Foul (EVAK Hippo 50), Sump Foul Pro (EVAK Hippo 100) and Sump FEKA (stainless) are all built around sewage pumps rated to pass solids.
When you install or alter foul drainage in England the work falls under Building Regulations, and Approved Document H is the guidance used to show compliance. In short: choose a pump specified for sewage rather than clean or grey water, size the chamber around the number of people it serves (a domestic figure of 150 litres per person per day, holding a full day's inflow in case of a fault), and use automatic operation for an unattended duty. Our full explainer is sewage pumps and Building Regulations, Approved Document H explained.
The 190 litre stations here suit typical domestic and small commercial foul duties. Where a larger population or higher demand calls for more storage, see the larger chamber sizes further down this page.
A packaged station makes an effective, permanent flood defence when it is set as a dedicated low point, for example behind a flood wall or barrier, or in a driveway, so water is collected and pumped away automatically.
For high-inflow sites, the Microforce is the highest-flow 230V station we supply, at 830 L/min. Designed for high inflow conditions, the Microforce system is ideal for sites at flood risk. It is not suitable for low-flow or small scale floods, to avoid rapid on/off cycling. This system should be installed with appropriate drainage connections to allow water to flow freely into the chamber. Should you desire a larger chamber, please contact us to request a quote.
In a basement, a packaged station collects and removes the groundwater that a Type C (cavity drainage) system channels to a low point. The Sump 635, in single or twin form, is our most popular choice for this, usually specified with a sealed lid. The twin gives built-in backup, which matters where a pump failure would mean water ingress. Learn how the system works in Type C cavity drainage explained.
The terminology causes a lot of confusion, so it is worth being clear.
A sump chamber is simply the chamber at the low point that collects the water. It can be formed on site, or it can be an existing chamber in a cellar. A packaged pump station is a pre-formed chamber supplied with the pump, internal pipework and non-return valve already fitted, so the components are matched and tested to work together. A site-constructed chamber suits refurbishments and connections into existing drainage, where size and depth are dictated by the construction. A packaged station suits new installations where you want predictable performance, easy servicing and a fast, low-risk install. For the full side by side, including cost, access and long-term reliability, read what is a sump pump and how do you install one.
A sump pump is not a distinct type of pump. The term refers to any pump designed to sit in a sump chamber, and in practice it is a colloquial name for an automatic submersible pump. You can browse ours in the sump pumps collection.
The real distinction is what the pump can pass. A clean or grey water pump is not built to handle sewage solids, which is why a foul duty needs a sewage-rated pump. We cover the difference in sewage pump vs sump pump: what is the difference, and what the solids ratings actually mean in pump solids handling explained.
Real installations, and the technical background behind them.
The stations listed above use our 190 litre Iguazu chamber, which covers the majority of domestic and small commercial installations. Larger chambers are available, from 300, 450 and 600 litres up to 8900 litres, in widths from 610mm to 1800mm.
Larger stations are almost always site specific. The chamber size and depth, the inlet arrangement, the number of pumps and the discharge route all depend on the flows involved and the levels on site, so they are supplied by quote rather than listed for sale online. You can size a below-ground chamber and request a quote here, covering foul, surface water, basement and rainwater applications.
For projects needing detailed design, hydraulic calculations or a site-specific pumped drainage solution, that work is delivered by our sister company FPS Environmental Ltd on a formal consultancy basis, so any engineered solution is based on proper site understanding rather than assumptions.
Most standard systems are available for fast dispatch. However, some pump stations are built or configured to order, particularly where specific chamber sizes or layouts are required, so next day delivery may not always be possible.
Pump station design and installation is site specific. You should always consult a suitably qualified engineer to determine the correct configuration and installation method for your application.
We supply equipment. We do not give site-specific design or installation advice over the phone, because the correct configuration depends on levels, flows, ground conditions and the discharge route, and those cannot be assessed without the full picture. Where a project needs calculations, a specification or a design, that is engineering work: see our engineering review service, or for a full design our sister company FPS Environmental Ltd delivers this on a formal consultancy basis.
If you wish to place an order by phone, call 0115 987 0358.
A sump pump is a single submersible pump that sits inside an existing chamber. A packaged pump station is a complete system, with the chamber, pump, internal pipework, non-return valve, and float switch supplied as one ready-to-install unit.
Clean water is rainwater, groundwater, and surface water. Grey water is wastewater from sinks, showers, and washing machines. Foul water contains sewage from toilets and requires a pump rated to handle solids, such as the Iguazu Foul, Foul Pro, or FEKA models.
Yes. We can supply alternative chamber sizes, inlet arrangements, twin pump systems, and different pump specifications beyond those shown here. You can size a chamber and request a quote with our below-ground pump station tool. For projects requiring detailed design or hydraulic calculations, our sister company FPS Environmental Ltd delivers these on a formal consultancy basis.
Discharge depends on the type of water and the property setup. Clean water and surface water typically discharge to a soakaway, ditch, or surface water drain. Foul water must discharge to a foul sewer or treatment plant.
Yes, in principle, but it depends on the floor construction and build-up. Indoor installations are common for basements, garages, and properties where external installation is not practical, but the structure must be suitable to accommodate the chamber and allow for correct installation.
For internal installations, and for any foul water system, a sealed and recessed cover should be specified to contain odours. This is available as an optional extra on the relevant models.
