Products Description
Need a medium-capacity vacuum conveyor for your growing production line?
Guanjiang's ZKS-4 Vacuum Powder Conveyor offers 2500 kg/h capacity — perfectly scaled for medium to large pharmaceutical, food, and chemical production. With a larger φ420×1216mm footprint and 5.5KW motor, it handles higher throughput while maintaining dust-free, GMP-compliant operation. The oil-free/water-free vacuum pump, automatic filter cleaning, and multiple filter options make it an essential component for standardized, clean workshop operations.
Key Advantages of ZKS-4
Powered by a 5.5KW motor, the ZKS-4 delivers 2500 kg/h throughput — ideal for medium to large production lines in pharmaceutical, food, and chemical industries.
The ZKS-4 features a larger φ420×1216mm vacuum hopper — fewer refill cycles and more continuous operation compared to smaller ZKS models.
Fully enclosed system eliminates dust emission — essential for pharmaceutical and food GMP certification. Promotes clean, standardized production.
Choose from polyester film-coated, PE, 316L stainless steel, or titanium metal filters — tailored to your material and hygiene requirements.

? Which Model Should You Choose?
ZKS-4 (2500 kg/h): Ideal for medium to large production lines where higher throughput is needed. The larger φ420×1216mm hopper means fewer refill cycles and more continuous operation compared to ZKS-1/2/3.
For higher capacities: Consider ZKS-6 (3200 kg/h), ZKS-7 (6000 kg/h), or ZKS-10-6 (6000 kg/h) — see table above.
Vacuum Conveyor FAQs
Q1: How does ZKS-4 differ from smaller ZKS models?
A: ZKS-4 features a larger hopper (φ420×1216mm vs φ290×mm) and a 5.5KW motor delivering 2500 kg/h capacity. It's designed for medium to large production lines, while ZKS-1/2/3 are suited for smaller-scale or R&D applications. The larger hopper means fewer refill cycles and more continuous operation.
Q2: Can ZKS-4 be used for continuous production lines?
A: Yes. The automatic level control and refill system enables continuous, unattended operation. The larger hopper capacity also means longer runtime between refill cycles, making it well-suited for 24/7 production environments.
Q3: What filter options are recommended for high-volume pharmaceutical production?
A: For high-volume pharmaceutical GMP applications, we recommend 316L stainless steel or titanium metal filters — they offer excellent durability, are easy to clean, and can withstand repeated CIP (Clean-in-Place) cycles. Polyester or PE filters are more economical for non-critical applications.
Q4: Can the ZKS-4 convey directly into large mixers?
A: Absolutely. The ZKS-4 is designed to convey materials directly into V-type mixers, two-dimensional mixers, three-dimensional mixers, and large ribbon blenders. The pneumatic discharge gate seals to the mixer inlet, ensuring dust-free transfer even at high throughput rates.
Q5: How is the ZKS-4 maintained?
A: The system has few moving parts, making maintenance straightforward. The automatic back-blowing filter cleaning extends filter life and reduces manual intervention. Access to the filter and hopper is via quick-release clamps for easy inspection and cleaning during scheduled downtime.
