Unica 4-270

Product catalog summary

Overview
The Unica 4-270 is a medium pressure double diaphragm pump designed as an effective alternative to piston pumps. It offers superior performance, high reliability, and innovative solutions for industrial applications.

Key Features

High Reliability: The pump features a special air-motor design with no internal friction and long-life diaphragms, reducing maintenance costs and minimizing downtime.
Excellent Finishing: Low pulsation output ensures high-quality finishing and a consistent spray pattern.
Sturdy Construction: Developed to meet high-quality standards with robust mechanical components.
Low Shear Effect: Ideal for circulating paint lines with minimal material degradation.

Exclusive Technology
The Unica 4-270 is equipped with a patented hydraulic circuit that minimizes diaphragm deformation and stress, ensuring long diaphragm life even under severe conditions. It operates with a 4.5:1 pressure ratio and a maximum working pressure of 27 bar.

Performance Benefits

Superior Power: Offers 50% higher working pressure than other pneumatic double diaphragm pumps.
Higher Performance: Reduced pressure drops along the stroke for stable material flow and higher working pressure.
