INTRODUCTION
The type POPL-I is a low-speed horizontal submersible flowmaker.
The unit is placed approximately in the middle of the cross section of the liquid and in operation it will provide
sufficient liquid velocity to maintain suspension.
During operation the mixer is locked by a conic stop console fixed to the guide pipe to obtain stability.
The mixing takes place by means of an electric motor coupled to the propeller (ø 67 inch or ø 91 inch) by means
of a planetary gear.
The oil filled coupling/oil chamber between motor and gear is in an open connection with the gear, so the oil
cools and lubricates the gear and the mechanical shaft seal between the oil chamber and the motor.
The hub is mounted on the propeller shaft, the output shaft of the gear.
The three propeller blades are adjustable for energy optimalization.
The exterior sealing system consists of three sealing rings with grease filled chambers between these.
The following pages describe the connection and the maintenance of flowmakers type POPL-I.
Application:
This flowmaker is to be used for flow creation, mixing and homogenization of liquids with a low dry matter
content, like e.g. wastewater.
The flowmaker can be placed in square and circular tanks and is to be applied only fully submerged below liquid
level.
If the flowmaker is to be applied for other purposes, contact Landia for advice.
WARNING - PLEASE NOTE THE FOLLOWING POINTS!
IMPORTANT !
Only a certified electrician is allowed to connect the unit.
IMPORTANT !
Prior to installation and start-up, check that the equipment is mounted
correctly to the flowmaker, as well as the equipment in the tank.
IMPORTANT !
Prior to the first start of the mixer, the propeller shaft must be rotated
manually. This also applies if the mixer has not been in operation for a
longer period.
IMPORTANT !
The electrical cable is always to be secured by means of the chain to
prevent the cable from getting into contact with the propeller. If the
flowmaker is not supplied with a chain, the cable is to be protected against
damage in another way, e.g. by means of a cable mesh.
IMPORTANT !
It must be verified that the propeller cannot touch the tank under any
circumstances.
