In-line pump dab CME-CM-GE-DCME-DCM-GE
In-line pump dab CME-CM-GE-DCME-DCM-GECirculation pumps with inline connections are designed for use in civil and industrial heating, air conditioning, refrigeration and domestic hot water recirculation systems. The MCE/C inverter provides maximum operational flexibility and performance, allowing the pump to automatically adapt to different system requirements and maintain a constant pressure drop.

DESIGN FEATURES
Single and double models are available. The suction and discharge connections are equipped with PN 16 flanges and threaded holes for pressure gauges or control sensors. Pump housing and electric motor support – cast iron, impeller – cast iron or technopolymer depending on the model (models with bronze impeller are available in sizes from DN 65 to DN 150). Hydraulic shaft – stainless steel steel. Mechanical seal graphite/silicon carbide standardized to DIN 24960 with EPDM O-rings. The pumps are equipped with a three-phase, four-pole, air-cooled electric motor. To ensure low noise levels and long service life, the rotor rotates on oversized bearings. The design of the electric motor complies with the requirements of CEI 2-3 standards.
