Model and Structure Description

250 WL 1000—22—110 250- Sewage mm WL- Vertical Sewage Pump 1000- Flow capacity m3/h 22- Head m 110- Power kW (1). The single foundation for motor can be used for the vertical pump. The long shaft is used to connect with pump. (The limiting speed is 1500 r/min). (2). If the center of pump volute is above the water surface (within the suction scope), the vacuum device can be supplied for the customer. (3). All the vertical pumps are explosion-safe types. (4). For the ordinary pump with the discharge diameter ranging from 65mm to 350mm, the base-plate with bend is adopted; for the vertical pump with the discharge diameter more than 350mm, the base-plate with straight pipe is adopted; for the base-plate of the rest pumps, require the customer to indicate. (5). For the high-pressure vertical, the packing sealing and the base-plate with straight pipe are adopted.
