Key Features for Industrial Applications
Superior Noise and Vibration Control
The SQP1ndesign incorporates Tokio Keiki’s proprietary noise-reduction technology. By utilizing a specialized multi-vane configuration and an optimized internal timing plate, the SQP1-11-1D-15 minimizes pressure pulsations at the source. This results in a significant reduction in airborne noise, making it one of the quietest pumps available for high-pressure industrial service.
Simplified Maintenance via Cartridge Kits
One of the most valuable features of the SQP series is its modular cartridge design. The entire rotating group—including the vanes, rotor, and cam ring—is contained within a single cartridge assembly. If maintenance is required, the cartridge can be swapped in minutes without removing the pump from its mounting or disconnecting the main hydraulic lines, drastically reducing downtime.
