and long maintenance intervals. A belt drive, toothed on both sides, replaces the timing gear that was previously common for rotary lobe pumps. Due to its complex design, this was prone to malfunctions and defects. In contrast to this, the new drive technology can even survive damage or blockages without major damage. In the worst case, the belt will come off or tear. If this situation occurs, only two screws must be released to remove the belt and replace it. Te robustness is also supported by the smooth running of the belt drive and the low vibrations during operation, because a hard-soft contact is always maintained between elastomer belts and metal gears. Tis provides gentle operation for all pump components. In addition, the drive works completely without oil, so that time- consuming oil changes and the risk of leaks are no longer a problem.
Te double-sided belt is not only used for transmission of forces from the motor to the shafts, however, it also synchronises the rotating motion of the lobes. Tis dual function has the great advantage of

simplifying the overall drive design considerably, which increases operational reliability while also saving installation space. In conjunction with the motor being flanged onto the top of the pump chamber, this provides one of the most compact pumps on
the market. Tis allows the pump to still be accommodated even in very confined spaces. Furthermore, there is no need for an extensive spare part stock for the belt drive, which helps reduce storage costs and downtimes to a minimum.
PUMP WITH “FULL SERVICE IN PLACE” CONCEPT

n addition to the robustness of the
T.Pro pump, easy maintenance was an essential
aspect for the ceramics manufacturer. The systems are designed so that they can be opened, cleaned and all wearing components can be replaced in situ without the pump having to be

disconnected from the supply. “As a result, maintenance and repair work takes very little time and downtimes of the system are reduced to a minimum,” Grainer continues. The T2 pumps also have a large housing cover that can be removed in just a few steps to provide open access to the entire pump interior.
The T2 pumps are designed for a long service life
