Tractor Pto Molasses Gear Pump


Portable tractor PTO driven gear pumps by K.I pumps. These pumps are ideal for pumping molasses, oils, tallows, fertilizers, bitumen, diesel, kerosene and other solutions. Use the power of your farm tractors PTO to pump a range of fluids including those with a very high viscosity.

      ♦ Transfer Pumps in 1.5”, 2", 2.5” and 3" sizes available with flow rates up to 26,460 L/hr
      ♦ High discharge pressures for long distance transfers
      ♦ Suitable for use with all type of tractors and pump


Every farmer knows the power and reliability of their tractor and power take off (PTO) system. No more messing around with small engines or maintaining a dedicated trailer pump engine, instead use your existing tractors reliable diesel engine and PTO system to pump oils, molasses and other highly viscous fluids. Quickly mobilize this pump on the back of your tractor to areas otherwise difficult to access. Engage the standard 540 rpm PTO shaft and the pump begins operation. Vary the PTO speed and engine rpm to change your discharge pressure and flow rate. Ideal for large transfer operations where time is of the essence.


When pumping molasses the key is to run these gear pumps at a maximum of 250 rpm. With the direct coupling to your tractor this is as simple as reducing the tractors RPM so the standard 540 rpm PTO speed is lowered. Molasses can be highly viscous when cold so care needs to be taken to ensure your pump is not starved of flow and this is best achieved by a elevated molasses supply tank, short suction lines and large diameters. Heating your molasses tank will also help it flow. Starving these pumps of supply can cause cavitation and eventual damage/destruction of the gears so it's important to monitor your operation especially when new.
