GN-20 Gerotor pump



 

Product designation: feed of foamed concrete, polystyrene concrete, paint and plaster mortars, paste fillers, emulsions, slimes and etc. to usage area. Gerotor pump is used for forcing feed of mixtures with fibro or solids of size up to 16 mm. application area: indoors and on construction sites.
Distance of mixture feed is up to 20* m vertically and to 100* m horizontally.
 
Design and operating principle.

 

The pump consists of frame, receiving hopper 1,2 m3, gerotor pair, drive mechanism with screw, gear motor and launching device. Gerotor pair includes stator and rotor.

 

 


 

 1 – receiving hopper, 2 – frame, 3 – gerotor pair, 4 – drive mechanism with screw, 5 – gear motor.

 
Mortar is fed to the receiving hopper and then by screw is supplied to the gerotor pair.  Then mortar is pumped through hose to casting place. Lifetime of gerotor pair depends on mortar composition, its abrasiveness and also on height and distance of mortar feed.
 
Note:   
*distance of feed is determined if there are two mitre elbows 90?? and mortar plasticity 13 cm acc. to GOST 5802-86.
