Wastewater pumping system provider Pump Technology has developed its new DrainMinor C automatic pumping system specifically for combi oven cleaning cycles, in response to requests from kitchen designers and users.
The DrainMinor C is designed to be compact and easy to use, with a low level inlet, and to enable reliable pumping and the ability to pump away multiple ovens or other requirements like a sink.
With an optional high-level alarm, it may be automatically monitored to ensure that potential flood or backup problems can be prevented.
The DrainMinor C package includes a compact, grey, rigid recyclable Polyethylene collecting tank. Its dimensions of H 322mm x W 300mm x D 290mm, should fit conveniently under a counter with access room. The lid covers the entire top of the tank and fits onto a captive seal. This should ensure that it is easy to see into the tank and all around the pump to facilitate removal of any debris from the cleaning cycle.
A 70mm ‘centre line’ low level inlet can be cut into the end or side of the tank to suit the oven drainage layout. Internal pipework and an 11/4” BSP non-return valve are included.
A submersible Jung Pumpen drainage pump is fitted with a low-level triangular float on an external rigid float arm. This is designed to ensure accurate and reliable automatic pump start and stop during the combi oven cleaning cycle. Because of this design it should not become jammed or restricted in the same way that an internal pump float system can.
The pump is fitted with a silicon carbide mechanical shaft seal, oil chamber and shaft seal ring. This should provide protection and long life for the pump when pumping hot waters and diluted chemicals, particularly when compared with a standard pump with a diaphragm shaft seal. The pump is also fitted with a self-venting port to ensure potential air locking from the turbulent discharge cleaning wastewater is prevented.
