About Hozelock Bioforce Revolution 12000 UVC
This is a Hozelock Bioforce Revolution pressurised external pond filter with an integrated UVC clarifier. The verified manufacturer documentation for part number 1352 (see manufacturer URL) lists an 18 W UVC lamp, an indicated maximum flow (Qmax) of 3,000 litres per hour and an installation restriction not to use a pump with a maximum head greater than 5 m. Hozelock present the unit as a pump‑fed pressurised filter that uses a removable foam bucket for mechanical filtration and biological media arranged around a central bio trumpeted chamber. The unit includes a diverter (Pond / Waste) for flushing, an internal winding handle system to assist cleaning, a UV‑interlock so the lamp is turned off if the housing is opened and a UV indicator lens to show lamp operation. Manufacturer guidance gives pond sizing guidance: up to 12,000 litres for ornamental/no‑fish ponds and up to 6,000 litres where fish are present (manufacturer table entries). The unit is supplied with a 5.0 m length of 3‑core cable and is rated IP57 with a maximum water temperature of 35 °C. Hozelock recommend using larger bore hose to avoid restriction and state that supplied hosetails accept Cypriflex hose in 25 mm, 32 mm and 40 mm diameters, recommending 40 mm where possible. Lamp replacement is stated as every 12 months. Note: the manufacturer documentation used for the technical values is tied to part number 1352. The supplied identity for this record uses the name/model values you provided; the technical fields below reflect what Hozelock publish for part 1352. Where Hozelock do not state a value for the assembled unit (for example total electrical power input or physical dimensions), those fields are shown as unknown.
Best for
Ornamental ponds up to 12,000 L (no fish) and fish ponds up to 6,000 L where a pressurised filter with integrated UVC is required
Things to consider
Manufacturer documentation for part number 1352 (the source used for all technical values here) maps part 1352 to Bioforce Revolution 6000 UVC. The supplied identity for this record names the model as “12000” with the same part code 1352; this cannot be reconciled using Hozelock’s published material. The numeric specifications in this record are the values Hozelock publish for part 1352. Hozelock do NOT publish the total electrical input power (watts) for the assembled unit, a detailed flow vs head performance curve for the filter, physical dimensions, operating pressure, or an explicit koi/heavy‑stock litres rating for part 1352 — those fields are therefore left null.
Installation
Follow Hozelock guidance: do not use a pump with a maximum head greater than 5 m or a pump flow greater than 8,000 lph with the Bioforce Revolution range; prefer 40 mm bore hose to avoid flow restriction; account for full static lift plus an allowance of 0.6 m for friction losses when selecting pump. Use the provided hosetails with compatible Cypriflex hose and observe the UV safety interlock during installation. Long hose runs and excessive vertical lift are warned against by the manufacturer.
Maintenance
Replace the UVC lamp annually as per Hozelock recommendation. The removable foam bucket can be rinsed/cleaned; biological media is located around the central bio trumpet and needs only periodic rinsing as described by the manufacturer. Observe manufacturer instructions for flushing via the diverter valve and for safe lamp replacement.
Safety
The unit is fitted with a UV interlock that shuts the lamp when the housing is opened; use this and follow all manufacturer safety procedures when replacing the lamp. Do not exceed the manufacturer maximum water temperature (35 °C). The unit is rated IP57—observe electrical safety and waterproofing guidance in the manual.
