General Description


The BSK diaphragm pump offers high volume delivery even at low air pressure and a b road range of material compatibility options available.Refer to the model and option chart.The BSK pump is provided with the modularized air motor and fluid section.

The air operated diaphragm pump alternately generates the intake fluid pressure and positive fluid pressure in the fluid chamber by using the pressure difference in the air chamber. The ball valve can ensure the forward flow of fluid.

Pump cycling will begin as air pressure is applied and it will continue to pump and keep up with the demand. It will build and maintain line pres -sure and will stop cycling once maximum line pressure is reached (dis -pensing device closed) and will resume pumping as needed.


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.


OPERATING INSTRUCTIONS


  • Always flush the pump with a solvent compatible with the material being pumped if the material being pumped is subject to “setting up” when not in use for a period of time.
  • Disconnect the air supply from the pump if it is to be inactive for a few hours.
  • The outlet material volume is governed not only by the air supply but also by the material supply available at the inlet. The material supply tubing should not be too small or restrictive. Be sure not to use hose which might collapse.
  • When the diaphragm pump is used in a forced -feed (flooded inlet) situation, it is recommended that a “Check Valve” be installed at the air inlet.
  • Secure the diaphragm pump legs to a suitable surface to insure against damage by vibration.

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 Teflon 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.

Installation dimensions:


Disassembly of the Parts in Fluid Section

a)First, remove the pump from the pipeline system and drain off the materials from the pump inside. b)Place the pump in a clean work environment. c)Dismantle the outlet pipe (1) from the pump first, and then take out the ball (2), O cup (3) and (47) and ball seat (4) from the upper end of the fluid cap (5) in sequence. After that, place the pump upside down and dismantle the inlet pipe (11) so as to take out O cup (3) and (47), ball seat (4) and ball (2) from the fluid cap (5). d)Release the bolts around the two fluid caps to disassemble the cap (5). e)Release the diaphragm screw (10) and remove diaphragm washer (7), (8) and diaphragm (6) from the both ends. Remove the diaphragm rod (23) and the lip-shape seal ring (25) can be replaced. Disassembly of Parts for Air Valve f)Loosen the bolt (39) first, and then dismantle the air valve casing (38), air baffle (42) and sealing gasket (40), and (41). g) Take out the valve slice (36) and valve plate (37) from the air valve casing (38). h) Dismantle the circlip (29) and take out the limit end cap (31) from both ends of the air valve casing (38), and you can replace the cup (30) as needed. i)You can check the lip-type packing (33) after pushing out the spool (35) from the air valve casing (38) with the hands. Disassembly of Parts for Pilot Valve j) Loosen 4 bolts (16) fixing the cylinder head first, and then dismantle the cylinder head (14) and (18) on both ends and remove the O cup (17). k) Remove the sealing gasket (19) from the groove of the motor casing (15). l) Eject the pilot rod (22) and trigger rod (45) from the motor casing (15) and you can replace the lip-type packing (20) on the trigger rod or the O cup (44) on the pilot rod. Reassembly of Diaphragm Pump The reassembly steps of the pump are incompatible with those of disassembly, so you are kindly asked to pay attention to the following in the reassembly process: 1) All the sealing elements, as well as their contact parts, must be greased. 2) Please check carefully prior to the use of all sealing elements whether they are damaged, such as surface damage. If damaged, please replace the new ones. 3) The lip direction of the lip-type packing (20)(, 25) and (33) should be consistent with the direction shown in the chart. 4) The bolts on the fluid cap should alternately be fastened by opposite angles to achieve a better sealing result. Troubleshooting 1. Some fluid is drained from the exhaust opening along with the air flow. Check the diaphragm for any damage. Check the diaphragm screw for looseness 2. There are Air bubbles in the outlet fluid Check the suction pipe connection for good sealing. Check the connection between the suction pipe and the intake manifold for good sealing. Check the O ring between the intake manifold and the fluid cap Check the diaphragm screws for looseness 3. Low pump output Check the air supply is stable. Check the inlet/outlet for any blockage. Check connectors connecting the intake manifold for air tightness Check that the ball is not stuck to the seat or the ball is not improperly seated. 4. Air is discharged from the exhaust opening when there is no reciprocating movement. Check seal ring (33) on slid valve (35). Check seal ring (20) on trigger rod (45). Check seal ring (25) on diaphragm link rod
