Pump Head Materials

Designed for maximum chemical compatibility and durability, a comprehensive range of pump head materials is offered, from stainless steel grades to high-performance alloys and engineered plastics.

Motor Variants

A full range of motor configurations is available, including general-purpose, variable speed (VFD), explosion-proof, and explosion-proof variable speed solutions for demanding applications.

Connection Variants

Engineered for seamless integration, the pump offers versatile connection options—including weld-end, flanged, threaded, and fully customized configurations to meet project-specific standards.

Control Variants

Delivering ultimate flexibility, the pump offers both manual and digital flow control, enhanced by servo-driven stroke precision and variable speed motor technology.

Multi Head Design

Engineered for operational flexibility, the system supports both centralized drive (one motor powering up to three pump heads) and independent drive (one motor per pump head) configurations.

Cooling or Heating Head

Enhanced process control with optional pump head heating or cooling systems for demanding temperature-sensitive applications.

Digital Lite Version

Intuitive backlit LCD interface featuring soft-touch controls, real-time flow monitoring (LPH), and resettable total flow tracking for enhanced operational visibility.

Digital Plus Version

Advanced touchscreen HMI interface with secure password protection, delivering full operational visibility including flow rate (LPH), totalized flow, pressure, level monitoring, pump status, and intelligent warning alerts.
