Marine Bilge, Freshwater & Macerator Pumps
From automated high-output submersible bilge pumps to smooth multi-fixture freshwater pressure systems, reliable fluid handling is vital for vessel safety and onboard living. Edric Marine carries top-rated commercial marine pumps from Rule, Jabsco, March Pump, Scot Pump, Grundfos, and Headhunter.
Engineered with marine-grade stainless shafts, moisture-resistant silicon seals, and ignition-protected heavy-duty permanent magnet motors, our pumps deliver maximum GPH flow rates, high suction lift, and dry-run tolerance designed for years of trouble-free operation.
Frequently Asked Questions
How many bilge pumps should a boat have?
ABYC guidelines recommend at least two independent bilge pumps for offshore boats: a low-capacity (500\u2013800 GPH) primary pump mounted at the deepest bilge point for nuisance water, and a high-capacity (1500\u20133700 GPH) emergency pump mounted several inches higher with a dedicated high-water alarm.
Can marine freshwater pumps run dry without burning out?
Modern diaphragm freshwater pumps (such as Jabsco Par-Max and Flojet) feature thermal overload protection and can run dry for extended periods without damage, unlike flexible neoprene impeller pumps which burn out within seconds.
What size discharge hose should I use for my bilge pump?
Always use smooth-bore marine hose matching the pump outlet diameter (typically 3/4", 1-1/8", or 1-1/2"). Corrugated bilge hose increases friction resistance, reducing actual pump discharge output by up to 30%.
How do I prevent siphon backflow through bilge pump through-hulls?
Install a vented loop in the discharge line well above the boat's heeled waterline, or mount the discharge through-hull well above the static and dynamic waterline to eliminate catastrophic siphoning.
