Technical Specifications
The document provides detailed specifications for magnetic drive pumps, specifically the EVT model. The pumps are capable of dry running when equipped with carbon impeller bearings. The maximum operating temperature varies depending on the material: PP (Polypropylene) at 80°C and PVDF (Polyvinylidene fluoride) at 98°C. The weight of the pumps is 6.00 kg for PP and 7.00 kg for PVDF.

Performance and Capacity
The pumps operate at two frequencies: 50Hz with a motor speed of 2800 RPM and 60Hz with a motor speed of 3450 RPM. The maximum capacity is specified in liters per minute (l/m), with a total head measurement provided. The performance curves for both frequencies are illustrated, showing flow rates against head pressure.

Construction and Materials
The pump body materials include PP and PVDF, while the impeller is made from ceramic or SIC (Silicon Carbide). The shaft is ceramic, and the impeller bearing is made from carbon. O-Rings are available in EPDM or Viton. Connections are available for both rigid piping and flexible hoses.

Components and Assembly
The document includes an exploded view of the pump components, detailing parts such as the suction nut, pump housing, impeller assembly, and drive magnet. It also lists the specific materials used for each component.

Installation and Connections
The pumps can be connected using socket fusion or butt welding techniques. The document specifies the dimensions and types of connections available, including socket unions and hosebarbs.
