About Hozelock Aquaforce 4000

The Hozelock Aquaforce 4000 (model 1582) is a submersible, solids‑handling pond pump intended for powering waterfalls, filters and fountain accessories. Manufacturer specifications list a maximum flow of 4,000 litres per hour and a maximum head of 2.5 metres. The pump is a fixed‑power unit rated at 50 watts and is supplied as a "Pump Only" product (no filter media or UVC). The unit is fitted with a removable inlet guard / wildlife protection system and a clip‑in fine mesh tray; the inlet arrangement allows adjustment of the strainer hole size (manufacturer references 6 mm / 10 mm and a WPS reducing to 2 mm). A multi‑step hosetail is supplied to accept 25 mm, 32 mm and 40 mm hose and the outlet also accepts 3/4" BSP screw‑thread fountain fittings. The instruction booklet and installation drawing describe the hosetail, ball‑joint and outlet adaptor arrangements and show how to cut the hosetail for the chosen hose diameter. Key operational limits given by Hozelock include a maximum permitted submersion depth of 2.5 metres, a maximum permitted water temperature of 35 °C and an ingress protection rating of IPX8. The small Aquaforce models (including the 4000) are not listed as amphibious. The pump includes automatic thermal overload protection (automatic cut‑out with reset procedure described in the instructions). Manufacturer documentation does not state cable length, physical dimensions, weight, a flow‑at‑head curve, or any manufacturer‑recommended pond/fish/koi capacities for this pump; those items are therefore not specified here.
