Installation Requirements for ZJ Series Slurry Pumps

Installation Requirements for ZJ Series Slurry Pumps

(1) Pre-Installation Checks Verify the model, parameters, and component completeness. Review the technical manual before installation.

Alignment

For horizontal pumps, use a two-stage grouting method. Ensure: Centerline alignment with the foundation (±2 mm tolerance). Levelness within 0.1/1000. Coupling Alignment Methods: Straightedge and Feeler Gauge:Máx. misalignment <000000>le; 0.10 mm. Dial Indicator:Runout <000000>le; 0.15 mm; gap variance <000000>le; 0.10 mm. For belt-driven units, maintain parallel shaft alignment via pulley adjustment.

Piping Configuration

Inlet Pipe:Match or slightly exceed pump inlet size to prevent cavitation/sedimentation. Include a gate valve and expansion joint. Outlet Pipe:Match pump outlet size. Install a gate valve and pressure gauge upstream of the first valve. Key Rule:Throttle flow only at the outlet—never the inlet—to avoid cavitation.

Seal/Cooling Water Lines

For mechanical seals, connect water lines per manual (pressure gauge side = inlet). Grease-lubricated bearings require no cooling water.
