Small bottom pump

Small bottom pumps (bilge pumps) are safety equipment required for small boats/yachts to discharge accumulated water (rainwater, leakage, splashing) from the bilge, preventing flooding and corrosion. The following provides an appropriate explanation of core parameters, types, selection, installation, and maintenance speed.

Core parameters (mainly 12V/24V DC)

Flow rate: Small ships commonly use 500-1100 GPH (about 1.9-4.2 m ³/h)

Voltage: 12V (mainstream), 24V (large ships)

Outlet: 3/4 "; (19mm) or 1-1/8 "; (29mm)

Head: about 1.5-3m, the higher the flow rate, the smaller the flow rate

Material: ABS shell, stainless steel shaft, anti-corrosion (based on actual reports) seal

Installation key

The pump body/suction port needs to be installed at a lower point at the bottom of the cabin

Use smooth hard pipes (non corrugated), shortened straight pipes, and stainless steel clamps

Install a one-way valve at the outlet to prevent backflow

Electrical: Add fuses, keep away from water sources, and do a good job of waterproofing (based on actual reports)

Daily maintenance

Monthly testing of automatic start stop function

When not in use for a long time, take it out and store it dry
