Important Warnings and Safety Information IMPORTANT Read these safety warnings and instructions in this manual completely, before installation and start-up of the pump. It is the responsibility of the purchaser to retain this manual for reference. This manual must be kept with, and supplied with the pump at all times. Failure to comply with the recommendations stated in this manual will damage the pump, and void factory warranty.
PRINCIPLE OF PUMP OPERATION This ball valve type diaphragm pump is powered by compressed air and is a 1:1 ratio design. The inner side of one diaphragm chamber is alternately pressurised while simultaneously exhausting the other inner chamber. This causes the diaphragms, which are connected by a common shaft secured by plates to the centres of the diaphragms, to move in a reciprocating action.
Trouble Shooting Guide & Technical Data TROUBLE SHOOTING GUIDE NOTE :- Check all solutions before dismantling the pump. PROBLEM Pump will not start CAUSE SOLUTION Air valve assembly malfunction/Seizure Obstructed fluid line. Obstructed diaphragm chamber. Diaphragm failure causing fluid & excessive air to be expelled through the exhaust. Diaphragm seal failure. Air valve system malfunction. Air connected to exhaust. Erratic flow Check carrier for freedom of movement. Clean, oil & replace.

This is signified using an ‘X’ in the last part of the pump code as shown.
Performance Curve B15 Pump performance curve Performance based on waterat ambient temperature Re-Assembly of Outer Covers When re-assembling the pump after any service or maintenance work, both Outer Covers must be re-torqued using the sequence shown above. The orientation of the pump is not important, providing the above sequence is followed. Failure to comply with these instructions may result in poor sealing and mis-alignment between the diaphragm sealing faces. HG-CF-1119 Rev. F – 10.12.

SERVICE The following sections give a general overview on how to service all models of BLAGDON Diaphragm Pumps. For details on individual part numbers, quantities, materials, etc., please consult the parts list supplied with the pump.
Atex Certified Models WARNING! WARNING! T a k e action to prevent static sparking. Fire or explosion can result, especially when handling flammable liquids. The pump, piping, valves, containers or other miscellaneous equipment must be grounded. In the event of diaphragm rupture, pumped material may enter the air end of the pump, and be discharged into the atmosphere. If pumping a product which is hazardous or toxic, the air exhaust must be piped to an appropriate area for safe disposition.
Wet Side Kit Structure Diaphragm Pump Wet-Side Kits - Part Number Structure The format of the Wet-Side kit part number has recently changed and is broken down as shown below. The numbers now start with ‘WSK’ followed by the model number, diaphragm letter, ball valve letter and pump material. If rubber seats are used, an ‘R’ is added to the end. A ‘W’ is added following the ball valve letter if pump is fitted with weighted balls. These are not available for sizes below 1”.
Service / Maintenance Log Date Details Completed Notes RECYCLING Many components of BLAGDON air operated double diaphragm pumps are made of recyclable materials. We encourage pump users to recycle worn out parts and pumps whenever possible, after any hazardous pumped fluids are thoroughly flushed. HG-CF-1119 Rev. F – 10.12.
