Loosen the lubricant drain plug, and slowly let the lubricant drain into a container for re-use or
disposal (lubricant should not be re-used if it is contaminated with the product). Replace the
drain plug when all lubricant has drained from the pump housing; check the condition of the
sealing washer
If the hose has ruptured, the lubricant may be contaminated with the product - care must be
taken to handle the mixture appropriately. It is not advised to re-use the lubricant once the pump
has run for 24 hours
• Remove the section of piping immediately connected to both inlet and outlet port flanges to
allow access. Place a container below the port flange to catch any remaining lubricant that
may be still in the pump
• The inlet port flange is held in place with four bolts, which should be loosened and removed,
in a criss-cross formation
• Pull out the port flange assembly and remove the insert and clamp rings (see fig 16 below).
Figure 16
• Clean all parts and check the insert and O-rings for wear or other damage. Replace sealing
rings every 2nd or 3rd hose change (supplied as a ‘ Flange sealing kit’ including O Rings)
• Repeat the above step for the outlet port flange
• Reconnect the power to the drive and slowly inch the drive forward a short distance. Check
the hose is completely free at both ends, then continue to inch the drive forward slowly to
expel the hose
Do not stand near the pump during this operation. If the hose is expelled too quickly it could
cause serious injury
• Inspect the pump for any spillage of product. It is recommended that the pump housing
should be cleaned, typically using a water jet, following hose removal, particularly if:
(a) leakage has occurred; or
(b) the product is aggressive / corrosive;
• Inspect hose for wear and damage and maintain a record of its condition and hours of
operation
