Frequently Asked Questions

Q: What is the flow rate of this 12V sewage macerator pump?

A: This pump has an open flow rate of 18.9 litres per minute (LPM), making it suitable for efficiently flushing and transferring toilet waste in marine, RV, and off-grid applications.

Q: Is this macerator pump compatible with standard RV and boat electrical systems?

A: Yes. The pump operates on 12V DC, which is the standard voltage used in most RV, caravan, and marine electrical systems. It can be connected directly to a 12V battery or power supply.

Q: What does "flexible impeller" mean for a sewage pump?

A: A flexible impeller pump uses a pliable, rubber-like rotor that bends as it rotates to create suction and flow. This design is highly effective at moving liquids that contain small solid particles — such as macerated toilet waste — without clogging, making it ideal for toilet and sewage flushing applications.

Q: Can this pump be installed in a horizontal orientation?

A: Yes. This pump is specifically designed for horizontal mounting, making it well-suited for installations where vertical space is limited, such as in boat bilges, under-sink cabinetry, or RV utility compartments.
