Marco UP2 Pump for gearbox or diff cooling systems. These Marco pumps use bronze helical spur gears for excellent suction and pressure. Made in Italy. No diaphragms to fail. Very quiet operation. These are a great alternative to the VDO or Tilton oil pumps.
UP2 Specs:
Up to 3.3L/min flow rate depending on hose sizing and fluid viscosity.
12 Volts, 2.0 - 2.5 amps current draw. Recommend 4amp fuse size.
Weight: 1.2kg (2.6lb).
Max Temp: 120c.
Fittings: 3/8 BSPP in pump housing.
Recommended plumbing setup for gearbox or differential cooling systems:
Housing -> Filter -> Cooler -> Marco Pump -> Housing.
This protects the pump from particulates that can jam in the gears, and it also cools the oil before going through the pump. This will result in exceptional pump reliability and lifespan. The Marco pumps have high scavenge/suction, pulling through a filter and cooler before it reaches the pump is not an issue. Maximum 100micron filter size recommended.
