About Evolution Aqua Airpump 95
The Evolution Aqua Airpump 95 is a diaphragm-style aeration pump designed for garden-pond use and other pond aeration applications. The manufacturer lists the pump’s maximum output as 95 litres per minute (stated by Evolution Aqua), which converts to 5,700 litres per hour; that converted L/h value is included here as a unit conversion of the manufacturer’s stated l/min figure. The pump has a single outlet with an M16 internal thread and the manufacturer’s dimension drawing labels the outlet diameter approximately Ø19 mm. Evolution Aqua recommends running larger internal-bore airline (8 mm ID or larger) from the pump to terminal points and documents the use of manifolds and sinking airline accessories. Manufacturer documents provide additional performance data such as a listed rated pressure (0.15 kg/cm2) and an operating-pressure range (0.1–0.25 kg/cm2), a published weight of 6.99 kg, and a noise level listed as <47 dBA. Dimensions shown on the official drawing include length 236 mm, width 181 mm and height 190.6 mm (with further labelled foot-spacing and mounting callouts on the dimension sheet). The product is described as weatherproof but not waterproof and the manual includes typical installation guidance such as mounting and anti-siphon measures. Evolution Aqua states a 2-year guarantee from date of purchase. Some manufacturer documents for this exact model present differing numerical values for certain items (notably maximum operating depth and power consumption). These conflicts are noted in the limitations section below rather than being resolved editorially here. Several common retailer or editorial fields (exact cable length, IP rating, and pond-capacity guidance) are not specified in the supplied Evolution Aqua documents and are therefore not asserted here.
Best for
Providing aeration to garden ponds and operating diffusers or air-driven aeration accessories (as documented by Evolution Aqua).
Things to consider
Manufacturer documents for this exact model contain conflicting values that are not resolved in the supplied sources. Evolution Aqua states a maximum output of 95 l/min (converted here to 5,700 L/h) but lists two different maximum operating depths (4.35 m on the product page/brochure vs 3.75 m in the instruction manual) and multiple inconsistent power/wattage figures across the product page, pump-curve PDF and instruction manual. Because the manufacturer sources contradict each other, maxHeadM and powerWatts are left null here rather than selecting one value. The exact mains cable length, IP/protection rating number, and any pond-capacity (general/fish/koi) guidance are not published for this model in the supplied Evolution Aqua documents and therefore are unknown.
Installation
Manufacturer guidance (from the instruction manual and product pages): operate within an ambient temperature range of 5 °C to 40 °C; do not situate where the pump is likely to be flooded; if the pump is mounted below water level a non-return valve MUST be fitted to prevent siphoning; elevate the pump where possible and do not cover it. Use large internal-bore airline (8 mm ID or larger) from the pump to distribution points. The outlet uses an M16 internal thread and the manufacturer supplies a rubber elbow for sinking airline connections; manifolds and multi-way splitters are shown in the documentation as supported accessories. No IP rating number is published in the supplied documents.
Safety
Thermal protection is fitted as standard (manufacturer statement). Observe ambient operating limits (5–40 °C), avoid locations where flooding can occur, fit a non-return valve when mounted below water level to avoid siphoning, and do not cover the pump. The unit is described as weatherproof but not waterproof; the manufacturer does not publish an IP rating for this model.
