MAK4 Water Pump

I'm using this MAK4 pump as the primary return pump, this time around the most powerful pump in the system will not be the return pump. Instead it will be the skimmer pump. I feel the turnover rate between tank and sump is not that critical and does not need to be very high. It is the in-tank circulation rate that is critical and needs to be high. In-tank circulation is being handled by the Tunze Turbelle Stream 6100 which provide 3175 GPH each.

Max. Flow: 19.7 Gallons Per Minute. (75 l/min)
Max. Head: 22.3 Feet. (6.8 m)
Rotation Speed: 3000 RPM.
Uses 55 watts at 60hz with 110 volts.

Input: 3/4 inch MPT
Output: 3/4 inch MPT

Length: 10.7 inches (272 mm)
Width: 3.5 inches (90 mm)
Height: 5.3 inches (134 mm)

This pump moves over 1190 gallons an hour at 4 foot of head pressure.

UPDATE: July 2005 - This pump was removed. The pump had a bad bearing and became very loud. This pump was replaced with an Iwaki MD55RLT Water Circulation Pump.
