CM Series: The design of these pumps enables its application on services where installation space is at a premium. These vertical in-line pumps can be assembled on straight pipelines. The inner pump parts (impeller, mechanical seal, wear rings etc.) are easily accessible without any need for the removal of the suction or discharge pipes. Furthermore, the CM series can be dismantled without removing the motor. General Applications Power plants Air conditioning and heating Cooling systems Water supply Irrigation systems Clear or lightly charged liquid pumping Marine General Service Pump: bilge, ballast, deck wash or fire fighting Fresh Water and Sea Water cooling of: main engine, auxiliary engine, gear box etc. Brine circulation and transfer Water circulation on condensers and fresh water generators Air conditioning and freezing services Harbour and shipyard services Main Pump Vertical single stage centrifugal pumps, In-Line execution. The pump can be assembled in confined spaces due to the suction and discharge flanges being in-line. The impeller is mounted 'reversed' with the suction facing upwards. This enables a better balance of the axial forces acting on the pump shaft supporting ball bearings. Priming Pump A liquid ring priming pump can be fitted, which has a high suction capacity. It has a compact design for simple maintenance and repair. Executions The CM-series of Bombas Azcue pumps are available in various builds (CM, CM-GR, CM-GF, CM-EP, CM-EF and CM-VP). They are constructed with a flexible coupling with spacer coupling so that the inner parts (impeller, mechanical seal etc.) can be maintained easily without removing the suction or discharge pipes, nor the electric motor. This version simplifies maintenance and repair and enables disassembly in a minimum of space. The pump shaft rotates in oversized ball bearings. For severe applications and extreme loads, there is the possibility to supply the unit in 'reinforced' execution (FR), with oversized shaft and ball bearings. CM Series No priming pump CM-GR series With priming pump and manual control valve with 'priming' and 'run' positions. The priming pump is driven by the main pump shaft and conical gears. CM-GF series Identical to CM-GR but with automatic changeover once priming is accomplished. CM-EP With Priming Pump and automatic unit stop once priming is complete. The priming pump is driven via an electric motor. CM-EF Identical to CM-EP but with a mechanical purger with float, to avoid discharge of liquid to atmosphere by the pump during priming. CM-VP Priming system by means of venturi ejector driven by air pressure
