Suitable for 1.5" size hose

Simple, compact design for all your water transfer needs

1.The all-plastic pneumatic diaphragm pump can not only pump flowing liquids, but also transport some difficult-to-flow media. It has many advantages of self-priming pumps, submersible pumps, canned motor pumps, mud pumps and impurity pumps.

2. No need to irrigate and divert water, the suction range is as high as 10m, the head is 70m, and the outlet pressure is ≥6kgf/cm2;

3. The flow is spacious, the passing performance is good, and the maximum particle diameter allowed is 4mm. When pumping mud and impurities, there is little wear on the pump;

4. The head and flow can be adjusted steplessly through the valve opening (air pressure adjustment is between 1-7kgf/cm2);

5.The pump has no rotating parts and no shaft seal. The diaphragm completely separates the pumped medium from the moving parts of the pump and the workpiece medium, and the conveyed medium will not leak out. Therefore, when pumping easy to play or corrosive media, it will not cause environmental pollution and endanger personal safety

Superior Performance: The self-priming 12V pump is equipped with an automatic pressure switch control that automatically opens and closes when you open and close the nozzle. It features 20 Liters per minute (5.5 GPM) capacity flow with a high pressure of 70 PSI and has built-in thermal overload protection.

High-quality Material: The 5-chamber positive displacement diaphragm pump's main body is made of ABS engineering plastic, one-piece, tightly sealed, and durable. A high-powered motor with a waterproof cover and a sealed pressure switch ensures that the pump operates in harsh environments. Rubber mounting feet reduce noise and prevent corrosion.

Complete Wash Pump Kit: This washdown pump kit includes a trigger Nozzle with Quick Connect, a Quick Connect Adaptor, a UV-protected 25' Coiled Hose, two NPT Connectors with 1/2" Straight Barb, and a Universal Saltwater Filter/Strainer.

Easy Connecting: This water dash pump has an externally threaded port pump head, available in various sizes, and can mount styles for easy connection to any outlet. The water pipe's threaded connection is made of high-quality brass, and the filter can be removed for cleaning.

Various Uses: The 12v water pump is designed for intermittent use with a duty cycle of 30 minutes and is suitable for fresh or saltwater. Ideal for cleaning boats, fish tanks, anchor chains, beacon stations, and boats. It can also be used to clean ships, RVs, and leisure decks.
