Keep reading about the Ronix RH-4042 Submersible Sewage Pump to see what makes it stand out!  

This pump has a compact and sturdy design that works best when fully placed underwater. It comes with a built-in handle for easy lifting and a G1 1/2-inch outlet to fit standard hoses. Everything about the design focuses on smooth operation, simple setup, and long-lasting use.

Inside, a 750W copper motor runs at 2850 RPM, giving you a steady water flow up to 13,000 liters per hour and a lifting height of 8.5 meters. The float switch automatically turns the pump on or off depending on the water level, saving power and preventing dry running.
It can handle dirty water with particles up to 35 mm, making it great for both clean and wastewater use.

The RH-4042 is safe to use and built to last.
It has an IPX8 protection level, meaning it can stay underwater up to 7 meters deep without damage. The thermal protector shuts the motor off if it overheats (at 125°C), while Class B insulation protects the inner wiring. Stainless steel screws and waterproof seals prevent rust and leaks, even with regular use.

This pump is ideal for a wide range of water-handling tasks. It can remove floodwater, drain domestic wastewater, empty tanks and pits, or manage water in gardens, ponds, and construction sites. Whether you’re a homeowner or a professional, the RH-4042 is designed to handle the job reliably and efficiently.

The pump comes in a Ronix color box that protects it during transport and storage. Included with the pump are one adaptor and a user manual, so you have everything you need to start using it right away.
