Embodiment Construction

[0029] The present invention provides a rotary lobe pump including a pump body and an insert. The pump body includes the parts of the pump that normally do not come into contact with the pumped material. The insert is the plastic part that includes the parts of the pump that come into contact with the material being pumped, namely the pump chamber and the lobe rotor. The insert is housed in and supported by the outer casing of the pump body.

[0030] FIG. 1 shows a rotary lobe pump 1 according to the invention. The lobe pump 1 comprises a pump body 3 and a plastic insert 5 .

[0031] The pump body 3 includes drive means in the form of a gearbox 7 . The gearbox 7 has an output shaft 9 at its one end and two output shafts 11, 13 at its other end. The gearbox 7 is configured such that the output shafts 11, 13 rotate at the same angular velocity but in opposite directions. The output shafts 11, 13 are provided with keys (not shown in the figure) for rotationally driving other...

Abstract

A rotary lobe pump comprises a pump body having a driving means and an outer casing, and an insert that can be replaced. The insert comprises: a housing formed of a plastics material and having an inlet port, an outlet port and internal surfaces defining a pumping chamber; and a pair of lobed rotors arranged for rotation within the pumping chamber. The housing includes apertures through which the lobed rotors may be rotationally driven, so that the lobed rotors mesh together for pumping a fluid from the inlet port to the outlet port.

Description

technical field [0001] The present invention relates to a rotary lobe pump. Background technique [0002] Rotary lobe pumps are positive displacement pumps used in industry for food, pharmaceuticals, and other similar materials. When handling these materials, it is important to avoid cross-contamination and chemical interaction with other materials. [0003] Known rotary lobe pumps provide a certain provision for dismantling by the user. In this way, parts of the pump that come into contact with the pumped material can be cleaned and sanitized in batches. The problems with such cleaning and sanitizing processes are that they are time consuming and error prone. Any errors in the cleaning process can result in contamination of the pumped material and / or loss of product. [0004] Typically, the components of a rotary lobe pump are manufactured with high dimensional accuracy and low tolerances. It is especially important that the shape of the lobe rotor and pump chamber wal...
