Lobe Pump
The Toss Rotary Lobe Pump is a reliable positive displacement pump for the gentle handling of sensitive process fluids. The pump is carefully engineered to provide reliable performance, trouble-free operation and superior energy efficiency for demanding applications. It is an excellent choice for duties that require contamination-proof pumps to meet high standards of hygiene, low-shear and low-pulsation operation. The pump is designed according to the most stringenthygienic design standards and with verified, effective Cleaning-in-Place.
High Efficiency
Heavy Duty
Adaptability
Less Noise
The Toss Lobe Pump is designed for gentle handling of sensitive process fluids across the dairy, food, beverage,brewing, chemical,
pharmaceutical, and home and personal care industries.Its smooth, low-shear pumping action makes the pump suitable for handling media of varying viscosities, whether low or high-from creams, gels, emulsions, and aerated mixtures to delicate cells and organic solids in suspension.The Toss Rotary Lobe Pump is available with 7 different pump head displacements based on different gearbox modules to handle flow rates up to 45 m3/h and differential pressures up to 7 bar.
- Consistent performance.
- Minimal risk of contamination.
- Low maintenance, increased process uptime.
- Modular design for greater flexibility to configure exactly
- The right solution for specific process requirements.
All media contacting steel components, like the rotor case,front cover, rotors and rotor nuts, are in SS316.The robust cast-iron gearbox provides maximum shaft rigidity and easy oil seal replacement. The gearbox design is universal, which enables the flexibility of mounting pumps with the inlet and outlet ports in either a vertical or horizontal planeby changing the foot and its position.
The standard Toss Rotary Lobe Pump has tri-loberotors. Optional bi-lobe rotors for handling fluids containing large delicate solids are available. Single mechanical shaft seals are available.The Toss Pump can be supplied either as a bare shaft pump or mounted on a base plate complete with coupling,guard, gear motor and shroud for easy, plug-and-play installation.
A gear train in the pump gearbox drives the rotors and provides accurate synchronization of the tri-lobe rotors. The movement of the counter-rotating rotors creates a partial vacuum that allows atmospheric pressure or other external pressures to force fluid into the pump chamber. As the rotors revolve, an expanding cavity forms, filling with fluid. As the blades disengage, each dwell forms a cavity. As the rotor blades engage, the cavity diminishes and fluid is displaced into the outlet port.
