Ultra-Compact Sump & Pit Pump Kit | APP BPS100EA, 134mm Wide
Built for the job
Compact sump and pit pump kit for tight chambers, shallow sumps and awkward access
134mm wide and 2.1kg, for the pits a full size pump will not go into.
This FPS Engineered™ kit pairs the APP BPS100EA automatic puddle pump with 10m of 25mm suction and delivery hose and a 20 to 32mm hose clip. Everything needed to put it in a chamber and start clearing water, in one order.
The BPS100EA exists for one reason: it fits where other pumps do not. At 134 × 170 × 250mm and 2.1kg it goes down openings that stop a full size drainage pump, sits in chambers too shallow for a taller body, and can be lifted in and out one-handed as many times as the job needs. It runs automatically on an integral float.
Part of our wider puddle pump, APP, pump kit and submersible pump ranges.
Is this the right kit for you?
Choose this pump kit when one of these is true:
- The opening or chamber is tighter than 160mm across
- The sump is shallower than about 300mm, so a 295mm body will not sit properly
- You are lifting the pump in and out repeatedly, super light weight at only 2.1kg
Any of those and this is the only one that will actually do the job.
At a glance
- 134 × 170 × 250mm: 26mm narrower and 45mm shorter than the RS32EA.
- 2.1kg: a genuine one-handed lift on a rope.
- 19mm and 25mm outlets: Takes standard hose, including a garden hose, as well as the 25mm supplied.
- Around 49 litres per minute at a 2m lift: Roughly 2,900 litres an hour through the hose supplied.
- Fully automatic on an integral float, with nothing to wire in.
- Handles 3mm solids, suited to clean and slightly dirty water.
- 304 stainless steel shaft and a carbon ceramic seal with an oil chamber, in a thermoplastic body.
- 2 year warranty from APP Pumps.
What's included
- 1 × APP BPS100EA automatic submersible puddle pump
- 1 × 10m length of 25mm suction and delivery hose
- 1 × stainless steel hose clip, 20 to 32mm
Reinforced suction and delivery hose rather than layflat, so it holds its shape in a chamber and will not fold shut against a wall.
What flow will I actually get at my lift?
Maximum flow and maximum head are the two ends of a pump curve and you never get both together. The figures below include the friction in the 10m of 25mm hose supplied.
| Vertical lift | Typical situation | Estimated flow | Per hour |
|---|---|---|---|
| 1m | Chamber out to a gully just outside | Approx. 54 L/min | Approx. 3,200 litres |
| 2m | Cellar or sump up to ground level | Approx. 49 L/min | Approx. 2,900 litres |
| 3m | Deep chamber up to a yard drain | Approx. 43 L/min | Approx. 2,600 litres |
| 4m | Lower ground up to street level | Approx. 36 L/min | Approx. 2,200 litres |
| 5m | Approaching the working limit | Approx. 26 L/min | Approx. 1,600 litres |
Estimated from the published 70 L/min and 6m figures, with hose friction by Hazen-Williams at C=130 across the 10m of 25mm hose supplied. Bends, kinks and worn hose cost a little more. To work out a specific run, use our pump performance calculator.
Which narrow pit kit?
Two kits, same job, and the choice comes down to whether the pump has to fit a tight space or move a lot of water.
| Kit | Body size | Weight | Max flow / max head | Hose | Choose it when |
|---|---|---|---|---|---|
| BPS100EA | 134 × 170 × 250mm | 2.1kg | 70 L/min, 6m | 19mm or 25mm | Tight access, shallow chamber, or lifting it in and out often |
| RS32EA | 160 × 170 × 295mm | 3.9kg | 130 L/min, 7m | 32mm | You have the room and want the water gone quickly |
Measure the opening rather than the chamber, because a cover frame, a benching or a grating you cannot lift is usually what stops a pump going in. If 160mm goes down it, the RS32EA kit is the better value. If it does not, this is your kit.

What can I use it for?
- Narrow inspection chambers and drainage chambers
- Shallow sumps where a taller pump will not sit
- Lift pits, service voids and ducts
- Cellars and basements with restricted access
- Utility rooms, under-stairs voids and boat lockers
- Light drainage and general water transfer
- Sprinkling and washdown work
- Emptying tanks, water butts and containers
- Trade clean-up where the pump is moved from job to job
Water quality limits
Clean and slightly dirty water, solids to 3mm. It is not a sewage or trash pump, and it is not recommended for ponds or water features. It is not intended for foul water, salt water, or liquids containing corrosive substances, fats, oils, flammable or explosive material. It does not treat or filter water, so nothing it moves is drinking water.
Setting it up
The discharge is on top of the pump and takes 19mm or 25mm hose. Push the supplied 25mm hose on and secure it with the 20 to 32mm clip. If you would rather run a garden hose for a light job, the 19mm outlet takes one.
Leave the float side clear. The float switch is built into the pump body rather than hanging on a lead, so there is nothing to site, hang or adjust. It does need a little space to work, so keep that face of the pump off the chamber wall and keep silt, rag and leaf litter away from it. Set the pump down, run water in, and watch it start and stop once before you leave it.
Lower it on a rope tied to the handle, never the cable. At 2.1kg that is easy, a real advantage of this pump.
Electrical safety
The plug connection must stay dry.
Connect the pump to a supply fitted with a residual current device, and keep the plug and socket connection out of the wet area entirely. Switch off at the socket before handling the pump or the float.
Frequently asked questions
What is the main benefit of this pump?
At 134mm wide, 250mm tall and 2.1kg it goes into chambers and openings that stop the RS32EA, and it is a genuine one-handed lift. If you have the room for a 160 × 170 × 295mm body, the RS32EA kit moves nearly twice the water for less money and is the sensible buy.
Will it fit my chamber?
The body is 134 × 170 × 250mm. Measure the narrowest point of the access rather than the chamber, and allow room for your hand and the hose on top. This is the smaller of our two narrow pit kits in both width and height.
Can I use a garden hose?
Yes. The pump has a 19mm outlet as well as 25mm, so an ordinary garden hose will fit for light work. The 25mm hose supplied in the kit will move more water, so use that where you can.
How low will it pump?
It is an automatic pump, so it stops when the float drops, clearing to around 3mm. If your job is getting a floor walkable rather than keeping a chamber clear, a manual puddle sucker is the better tool.
Can I leave it in permanently?
Yes. On an integral float it will hold a small chamber clear for long periods without attention. Give the float clear space, keep the plug connection dry and out of the chamber, and check it a couple of times a year.
Is it strong enough for trade use?
It is built for light trade and domestic drainage: a 304 stainless steel shaft, a carbon ceramic seal with an oil chamber, and a water cooled thermoplastic body. For heavy site water, continuous duty or anything gritty, step up to our site drainage pumps.
