Installation operation and maintenance:
READ, UNDERSTAND, AND FOLLOW THIS INFORMATION TO AVOID INJURY AND PROPERTY DAMAGE
Do not exceed the maximum inlet air pressure as stated on the pump model plate.
The limit pressure specified in the Manual can’t be used in the operation of the pump, otherwise the personal injury, pump damage or property loss will arise out of excessive air pressure.
STATIC SPARK. Can cause explosion resulting in severe injury or death. Ground pump and pumping system.
The discharges from the pump may contain impurities, which may cause serious injury. The discharges can be drained away through the pipe from the jobsite and around the operator.
Even if the diaphragm ruptures, it can also discharge the material forcibly from the exhaust muffler.
HAZARDOUS PRESSURE. Can result in serious injury or property damage. Do not service or clean pump, hoses or dispensing valve while the system is pressurized. Disconnect air supply line and relieve pressure from the sys -tem by opening dispensing valve or device and / or carefully and slowly loosening and removing outlet hose or piping from pump.
HAZARDOUS MATERIALS. Can cause serious in -jury or property damage. Do not attempt to return a pump to the factory or service center that contains hazardous material. Safe handling practices must comply with local and national laws and safety code requirements.
Explosion Hazard: Some models, together with some parts that fluid contacts, are made of aluminum, so they can’t be put into use with trichloroethane, methylene chloride or other halogenated hydrocarbon solvents, otherwise they may react and cause an explosion.
Verify the chemical compatibility of the pump wetted parts and the substance being pumped, flushed or re -circulated. Chemical compatibility may change with tempera -ture and concentration of the chemical(s) within the substances being pumped, flushed or circulated. For specific fluid compatibility, consult the chemical manufacturer.
Maximum temperatures are based on mechani -cal stress only. Certain chemicals will significantly reduce maximum safe operating temperature. Consult the chemical manufacturer for chemical compatibility and temperature lim -its.
Make sure that all the operators of this equipment have been specifically trained, grasped the safe operating practices and understood the limitations of the equipment. They know how to wear PPE if needed.
Do not use the pump for the structural support of the piping system. Be certain the system components are properly supported to prevent stress on the pump part
It is a must to prevent unnecessary damage to the pump. If it has to lie idle for a long time, please clean it thoroughly after each use.
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.

FLUID SECTION DISASSEMBLY
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.
FLUID SECTION REASSEMBLY
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
