Pond Pump
Evolution Aqua Varipump 10000
Model: 10000
A controllable/variable-flow submersible pond pump with a manufacturer-stated maximum flow of 10,000 L/h and a wired control box for adjusting output and monitoring instant wattage. Manufacturer documents contain conflicting values for maximum head and power.
About Evolution Aqua Varipump 10000
The Evolution Aqua Varipump 10000 (VP10) is a variable-flow, submersible pond pump that is supplied with a wired control box allowing the user to set flow from 0–100 and to view instantaneous wattage. Evolution Aqua publishes a maximum flow of 10,000 L/h for this model. The pump unit itself is rated IPX8 (suitable for submersion) while the control box is IPX4 and must be installed weather-protected (the control box must not be submerged). The Varipump is provided with a stepped hosetail to accept multiple flexible hose sizes (38 mm / 32 mm / 26 mm) and can connect to 40 mm (1½") pressure pipe; the manufacturer advises using the largest diameter and cutting off smaller steps where appropriate. External dimensions for the pump are provided by the manufacturer (267 × 122 × 162 mm). The product is described in official materials as using sine-wave motor technology and offering adjustable flow control via the supplied controller. Manufacturer documentation contains some explicit conflicts for this specific model: the product page and brochure list a maximum head of 5.5 m and a maximum power of 90 W, while the Varipump master manual lists the same model with a maximum head of 3.1 m and a maximum power of 75 W. Because both values appear in first‑party Evolution Aqua materials and no single authoritative value is confirmed, those fields are left unresolved here. Other manufacturer-supplied facts include cable arrangements (control box and pump cabling) and IP ratings, and a two year warranty stated in the Evolution Aqua brochure. Evolution Aqua does not provide manufacturer-rated pond, fish or koi capacities for this pump model, nor a pump weight in the supplied documentation.
Best for
Situations requiring adjustable/variable flow in a garden pond where a submersible pump with a weather-protected wired control box is acceptable (pump-only applications where variable output and instant wattage monitoring are desired).
Things to consider
There are explicit conflicts in Evolution Aqua's first-party documents for this exact model: the product page and brochure list Max Head = 5.5 m and Max Watts = 90 W, while the Varipump master manual lists Max Head = 3.1 m and Max Watts = 75 W. Because both sets of values are present in official materials and no single authoritative value is identified, maxHeadM and powerWatts are left null here. Manufacturer documentation does not provide pump weight, manufacturer-rated pond/fish/koi capacities, operating pressure in bar/psi, or any integrated UV/UVC wattage. The master manual also contains an ambiguous temperature advisory line (‘Do not use when temperatures are less then 0°C and 35°C’); the manufacturer text is presented verbatim in the source but is not clarified in the supplied documents.
Installation
Control box must not be submerged and should be installed in a weather-protected location. The pump is not self-priming; for non-flooded installations a non-return/check valve is recommended and the inlet/pump must be primed before startup. Do not operate the pump without water. Manufacturer shows two cable sections (2.0 m mains→control box and 10.0 m control box→pump). Use the largest hose diameter when using the stepped hosetail and cut off smaller steps as advised.
Maintenance
Manufacturer documentation supplied does not state maintenance intervals or specific servicing schedules for the Varipump 10000 in the provided materials.
Safety
The motor must be earthed and all electrical work should be carried out by a qualified electrician; an RCD (≤30 mA) is recommended by the manufacturer. Do not operate the pump dry. The control box is weather-resistant (IPX4) but must not be submerged; the pump is suitable for submersion (IPX8). The master manual contains a temperature advisory line presented verbatim but unclarified in supplied documents.
