GLYCOL PUMP

Repair Guide

STEP 18

CHECK VALVE CAPS

Replace if clearance between the cap and Check Valve

is too much.

Note: Take a check valve and slide it into a cap. Check for

side to side play and make sure the check valve goes in

and out freely. A good way to check side to side play is to

check for play with new parts to be able to tell the

difference (Fig. 18.1)

Repair if there is interference between cap

and check valve (to clean Check Valve Cap, insert

appropriate size reamer), or if O-Ring gets stuck up in the

communicating hole.

NOTE: Make sure communicating hole is clear. That can

be done with an air nozzle or a small drill bit. (Fig. 18.2)

STEP 19

CHECK VALVES

Replace if there is damage on the O-Ring ledge or stem

(Fig. 19.1).

NOTE: Inspect Check Valves for wear on stem and ledge

that holds the O-Ring. Sometimes when O-Ring comes off

the darts start hammering creating damage

to the ledge.

STEP 20

SUCTION BLOCK

Replace if O-Ring surface of wall has grooves or excessive

wear. (Fig. 20.1)

NOTE: When installing seats in to the block make sure

there is some resistance.
