General Description

Requirements for Air and Lubrication

EXCESSIVE AIR PRESSURE. Can cause pump damage, personal injury or property damage.

• A filter capable of filtering out particles larger than 50 microns should be used on the air supply. There is no lubrication required other than the “O” ring lubricant which is applied during assembly or repair.
• If lubricated air is present, make sure that it is compatible with the “O” rings and seals in the air motor section of the pump.

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.

FLUID SECTION DISASSEMBLY

• Remove the upper and lower manifold (1) and (11).
• Remove the ball (2), “O” ring (3) (47) and ball seat (4).
• Remove the fluid cap (5).

NOTE: Only diaphragm models use a primary diaphragm(6A) and a backup diaphragm(6). Refer to the aux iliary view in the Fluid Section illustration.

• Remove the screw (10), washer (9), diaphragm (6A, 6) and diaphragm washer (7, 8).
  NOTE: Do not scratch or mar the surface of (23) diaphragm rod.

FLUID SECTION REASSEMBLY

• Reassemble in reverse order.
• Clean and inspect all parts. Replace worn or damaged parts with new parts as required.
• Lubricate (23) diaphragm rod and 25) “Y” ring with grease.
• Fix the diaphragm rod (23) with the auxiliary installation tool.
• Prior to the final fastening of bolts and nuts, please determine whether the diaphragm (6A,6) is aligned with the fluid cap (5) properly to avoid the twisting of the diaphragm.
• For the models using diaphragm: three rubber diaphragms (6) on the side, which are marked with AIRS SIDE "air chamber" are mounted in face of the pump body.
• Start the pump, check the fastening and sealing after it runs for a period of time
