Single stage double pump with spiral pump body in inline design. The suction and discharge ports have the same diameter. The pump and the motor are directly connected to each other. The double pump has two pump heads arranged in parallel. The pumps are designed according to the top-pull-out principle, i.e. the pump head (motor, head piece and impeller) can be easily removed for maintenance or servicing, while the pump casing remains in the piping. Each pump head is equipped with an unbalanced rubber bellows seal. The mechanical seal complies with EN 12756. Piping connection via DIN flanges PN 16 according to EN 1092-2 and ISO 7005-2. Each pump head is equipped with a fan-cooled asynchronous motor of the same size and power.
