We are engaged in manufacturing high precision engineered Lobe Pumps which are used to unload and transfer fluids from barrels and ships. These lobe pumps are equipped with speed reduction features which offer a smooth flow with no pulsations, low noise and vibrations. Our pumps come in two choices of seals – mechanical seal and oil seals.
We offer the following lobe pumps:
An internal lobe pump unit consists of an inner and outer rotor. The inner rotor has one teeth lesser than the outer rotor. Tushaco’s RT and RTBP series uses a trochoidal inner rotor and an outer rotor formed by a circle with intersecting circular arcs. The inner rotor is located off-center and both rotors rotate. During part of the assembly's rotation cycle, the area between the inner and outer rotor increases thus creates a vacuum. This vacuum creates suction, and hence, this part of the cycle is where the intake is located. Then, the area between the rotors decreases, causing compression. During this compression period, fluids can be pumped, or compressed (if they are gaseous fluids).
Smooth rolling action of the rotors results in minimum noise, vibration and pulsation - less flow.
