METERING PUMPS VELON
VELON is a state-of-the-art compact peristaltic dosing pump, equipped with a high-precision, electronically-controlled multifunction stepper motor that guarantees constant and regular chemical product dosing, even in demanding working conditions and with load variations. Designed to offer a complete, easy-to-use solution in all installation contexts that require precise, reliable, quiet and safe operation.
Thanks to stepper technology, it is possible to vary the rotation speed and therefore modulate dosing in real time within a range from 1% to 100%, making it ideal for environments where a wide dosage range from 18 cc/h to 12 l/h at 2 bar is required.
It is capable of controlling and automatically dosing chemicals according to the parameters detected, dynamically adapting to the needs of the system. Through a wide range of dosing modes, it is able to adapt to the most varied operational requirements of the system. Maintenance activity meters make it possible for you to schedule pipe replacement in advance based on wear, while the easy pipe change system makes the operation quick and completely safe.
The wide range of variants (MF, PO, CL, PM) offers the utmost versatility and ease of use in a variety of contexts, while multi-channel connectivity makes VELON a solution that can be adopted in any working environment. Where remote intervention is required, VELON can be accessed and managed in all its functions via the Nimbus portal or through the MyEmec app.

PRISMA STEPPER METERING PUMPS
The PRISMA dosing pump is the best solution for the highest precision dosing with extreme reliability. The versatile stepper motor and sophisticated MultiFunction software offer absolute control over dosing speeds and working modes, as well as high flexibility.
The ENCODER control knob allows easy navigation through configuration menus and control and adjustment of working parameters. The backlit display can also signal different working states: pump running; stand-by; warning; alarm.
TURNDOWN RATIO
PRISMA pumps offer extremely precise control with an incredible turndown ratio of up to 4800:1. This allows the dosing process to be subdivided up to a maximum of 4800 steps to enable the most precise and even distribution of the product to be dosed.
SLOW MODE.
The Slow Mode function, when enabled, allows the suction speed to be reduced from 100% to 1% of normal speed, making priming and dosing easier, more reliable and accurate even with very viscous liquids.
