Marco continously expands and improves its line of reversible gear pump products. Our "E" series electronic sensor pumps offer a unique control which allows either a 12 or 24 volt DC (110 or 220 volt AC) power supply, along with a built-in fuse. These pumps will shutdown if they run dry, and electroncially sense demand to automatically increase or decrease the motor speed depending on fluid viscosity or water demand.
Marco's new and advanced oil change systems are constructed from all metal components, They deliver a powerful and rugged fluid transfer solution with 3-6-9 valve units as a standard. These units include the "E" Series electronic flow sensors and 12-24 volt DC power source option, so one system is suitable for all your marine or industrial applications. The E-sensor controls the speed of the motor in relation to the oil viscosity.
WATER PUMPS & WASHDOWN SYSTEMS
Marco water pumps and washdown systemsoperate at a continuous pressure and flow. Reliable internal Teflon gears provide corrosion-resistant performance, and the pumps have no internal diaphragms or rubber parts to wear out. We even offer a dual pump system which will automatically activate the second pump if demand exceeds the first pump's flow rate.
