Heavy Duty Multi-stage vacuum pump without control, CMSHD_NVO_
COVAL's multi-stage vacuum pumps CMSHD__NVO combine performance, robustness and modularity.
Equipped with a multi-stage venturi system, the CMSHD__NVO vacuum pumps ensure powerful suction flows and high consumption/performance efficiency, promoting energy savings.
Each component has been designed and tested in real-world situations to meet the harshest environments. Thus, the pumps are IP65 and guaranteed for more than 50 million cycles.
The modular design of the CMSHD__NVO enables to target interventions on each of its elements, reducing both costs and response times.
