This is the industrialcraft pump I presume not buildcraft, and it doesn't have upgrade slots for overclockers.

If you want to supply water to a compressor to make snowballs then you can use multiple pumps. Not much of a solution but it helps.

If you want to fill water cells in bulk then I would suggest an automatic crafting table mk1 and a deployer. The deployer fills buckets and the mk1 table will use the bucket and return it to the deployer.
