In-line twin pumps with frequency control
Single-stage, without coupling, centrifugal with suction and exhaust pipes on the same line. The twin pump is designed with two parallel heads. The pump has a top extraction design, i.e. the head part (electric motor, pump head and impeller) can be dismantled for maintenance or repair while the pump body remains on the pipeline. Each working head is equipped with an unbalanced rubber bellows seal. The shaft seals comply with EN 12756. Connection to the pipeline using PN 16 DIN flanges (EN 1092-2 and ISO 7005-2). Each identical-sized head is equipped with a fan-cooled asynchronous electric motor. The electric motor includes a frequency converter and a PI controller in the terminal box. This ensures constant smooth control of the motor speed, as well as the ability to adjust the performance characteristics accordingly
