- PID Control Box
Used In pressure sewage system.
Drainage of wastewater from individual residences,
apartment buildings, recreational developments, models.
Transferring wastewater of commercial buildings，industrial plants，
wastewater sampling, small hospitals.
Schools, federal, state and local parks, wastewater drainage.
To transfer various wastewater and sewage.
The pump has a semi-open impeller design with a reliable grinding system.
The large-diameter impeller generates a high pressure and the grinding system
grinds solids into small pieces, which can be drained without clogging the pipes.
The pumps can be connected to pipes directly or to an auto-coupling system.
