Light Wight Air Driven Double Diaphragm Pump Movable 70m Maximum Lift

Double Diaphragm Pump introduction

Air operated double diaphragm pumps not only can exhaust the flow liquid , but also can convey some uneasy flowed medium.

• it’s unnecessary to pour the drawing water. The suction lift reached 7MM height, the delivery lift reaches 70M length and export pressure
• wide flow and good performance ,the diameter allowed pass the max grain reaches 10MM ,the damage is very less to the pump while exhausting the slurry and impurity.
• The delivery lift and flow can pass the pneumatic value open to realize the stepless adjustment.
• This pump has no rotary parts and no bearing seals, the diaphragm will completely separate the exhausted medium and pump running pollution and human body safety dangerous while exhausting the toxin and flammable or corrosive medium.
• No electricity , it’s safe and reliable while using in the flammable and explore places.
• It can be soaked in medium.
• It’s convenient to use and reliable to work . only open or close the gas value body while starting or stopping, Even if no medium operation or pausing suddenly for long time because of accident matters, the pump will not be damaged caused by this. Once over-loading ,the pump will automatically stop and possesses the self protection function, When the load recovers normally , it also can star automatically.

Maintenance

• Please refer to the component schematic in the assembly drawings to look up the serial numbers and names of parts and grasp the information of parts and maintenance service pack.
• Some BSK parts are marked as "wearing parts", which can conduce to quick service and downtime reduction.
• Service kits are divided to service two separate diaphragm pump functions: 1. AIR SECTION, 2. FLUID SECTION. The FLUID SEC -TION is divided further to match typical part MATERIAL OPTIONS.
• Provide a clean work surface to protect sensitive internal moving parts from contamination from dirt and foreign matter during service disassembly and reassembly.
• Keep good records of service activity and include pump in preven -tive maintenance program.
• Before disassembling, empty captured material in the outlet man -ifold by turning the pump upside down to drain material from the pump.
