E-SERIES SENSOR PUMPS

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.

TRANSFER & OIL CHANGE SYSTEMS

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.
