Operation and Maintenance Guide  SDP 25 Metal Series

Maintenance

Regular inspection and maintenance schedules will greatly enhance the life of the pump and 

will ensure a trouble free and safe working environment with little chance of breakdowns.

Follow the instructions clearly in “Disassembly and Reassembly”of the pump and in the 

troubleshooting section.

Use genuine Teryair  spares and if possible mention the serial number of the pump when 

ordering spares.

Always replace elastomers as a set, eg diaphragms, balls and seats.

Disassembly and Re assembly

•  Shut off air supply and allow residual Pres-

sure to bleed off.

•  Disconnect air supply
•  Disconnect suction and discharge piping
•  Turn pump upside down allow process fluid 

to drain away. If fluid is hazardous due care 

should be taken.

•  Make a mark to indicate the positioning of 

each liquid chamber relative to the housing.

NOTE: Replace worn parts with genuine 

TERYAIR parts for reliable performance.

1. Replacement Of Diaphragms, Ball 

& Ball Seat.

a.  Unscrew the four manifold bolts (19) & nuts 

(18). Remove the top and bottom manifolds 

(3 & 2). 

b.  Inspect manifolds (2 & 3), O-Ring (14), and 

valve balls (13). If swelling, cracking or  

other damage is apparent, these parts must 

be replaced with genuine TERYAIR parts 

 

Note:  For SS Models inspect Ball Seal (14), 

Ball Seat (14A), Ball cage (14B) & Ball (13). 

If swelling, cracking or other damage is 

apparent, these parts must be replaced with 

genuine TERYAIR parts.

c.  Now unscrew hex socket head bolt (21) 

& nut (20) of any one side and proceed to 

remove the big clamp (7). Now remove the 

outer chamber (4). Now repeat the same 

procedure to remove the second outer 

chamber.
