Energy-saving filter press feed pump for replacing screw pump in slurry handling applications
To meet customer needs for replacing screw pumps in filter press systems, we developed a custom horizontal plunger pump specifically designed for the narrow and elongated installation spaces typical of screw pump layouts. Based on on-site operational feedback, the redesigned horizontal plunger pump ensures adequate maintenance clearance, stable operation, low noise, and zero vibration, earning consistent positive feedback from clients.

Features
- Energy saving: Compared with traditional slurry and screw pumps, the horizontal plunger pump reduces motor power consumption by 50%–80%, significantly lowering operational costs.
- Higher pressure and efficiency: The pump delivers output pressure up to 2 MPa, greatly improving filtration efficiency, increasing filter cake thickness, and reducing moisture content.
- Upgraded sealing and guiding structure: A universal joint absorbs misalignment between the hydraulic cylinder, coupling, material cylinder, and mounting frame, effectively reducing seal-ring wear.
- Custom sealing materials: Built with specialized sealing materials and structures to greatly extend seal life.
- Smart lubrication system: Timed and metered lubrication is applied between guide seals through a closed-loop lubrication system, preventing oil waste and environmental contamination. Controlled lubrication also avoids accelerated seal wear caused by human error.
- Longer service life: Low-speed reciprocating (back-and-forth) motion extends the lifespan of core components compared with high-speed reciprocating pumps.
- LED status indicators: Visual LED lighting indicators allow operators to quickly identify pump status by color. Commands are issued, processed, and monitored through the integrated PLC system.
- Optimized for narrow installation spaces: The pump is specially customized for elongated and tight spaces typical of screw pump applications while ensuring sufficient maintenance access, stable operation, low noise, and vibration-free performance.
