Group Pressure Variation Speed EH ETech-Nastec

Pressure Group with Speed Variation E-Tech by Franklin / Nastec formed by the equipment described below:

1. Two E-Tech-Franklin electric pumps of American origin, model EH, made up of monobloc horizontal centrifugal pumps, equipped with an electric motor for current 1~230 Volts, 50 Hz, 2890 Rpm, horizontal assembly with turbines and diffusers in 304 stainless steel.
2. Autoclave tank with a capacity of 8 Lts, with food-grade rubber membrane pre-loaded with air, with cupped bottoms.
3. 2" stainless steel 304 compression manifold.
4. 2" stainless steel 304 suction manifold.
5. Check valves on each pump.
6. Compression isolation valves for each pump.
7. General shut-off valve.
8. foundation
9. An electrical power cabinet, comprising groups of circuit breakers, main switch, terminal strip.
10. Two pressure transducers.
11. Two variable speed drives of the brand Nastec model MIDA , of Italian origin, installed on the electric pumps. MIDA is a frequency converter dedicated to MIDA hydraulic flow control in areas.

The operation of the variator meets the most demanding demands for comfort through constant flow or proportional pressure (compensation for increase and load losses in the network due to the increase in flow), smoothly supplying the required flow without current peaks or water hammer due to smooth starting and stopping. This system reduces energy costs and maintenance costs.
