This product has now been moved/updated. Please see the link below to see the new pump chain options.
Designed with corrosion resistance in mind, we offer pump lifting chain slings made from galvanised grade 40 steel, 316 stainless steel or from grade 50 316L stainless steel for more aggressive environments in safe working loads up to 6300kg (contact us for greater capacities) and working lengths to suit our customers individual requirements.
These special pump chains are for raising and lowering of submersible pumps from boreholes, waterworks, sewerage treatment facilities and many other below ground locations either for routine maintenance or to perform out essential repairs; a very popular, if not essential piece of lifting equipment used by water authorities world wide!
The design incorporates a length of chain with a master Link at each end and another larger anchorage link (master link) every meter; the reason being that these pumps are often in isolated locations where manual portable lifting equipment needs to be used to retrieve the pump, such as a hand chain block and a tripod. Because the tripod is only usually about 2 metre tall and the water well / borehole is many metres deeper there needs to be a master link every metre so that when the pump has been lifted as far as it can the chain sling can be anchored on to an ancillary hook hanging (on the tripod head) allowing the hoist to be re-located on the next master link below; the whole procedure is then repeated as many times as is required to raise the pump!
We also offer special made to order pump lifting chain assemblies with over-sized master rings and other chain components. Contact our sales team for more information.
Choosing The Correct Sling: Galvanised Grade 40, Stainless 316 or Stainless Steel 316L
Grade 50, 316L is a higher grade Stainless Steel than normal stainless steel grade 316 , with a lower carbon content and higher alloy content. It is predominantly used for Lifting operations and now more frequently used in the Utility market for Pump Lifting Chains. We previously sold predominantly normal 316 Stainless Steel Pump Chains but now the swing seems to be towards Gr.50 grade 316L as more and more Utility companies write the Gr.50 spec. into their own Pump Lifting Specification. The higher price is reflected due to the higher alloy content and restricted supply of this chain (Gr.50 Chain is only manufactured in Europe).
All options; Galvanized, 316 & 316L (Gr;50) Pump Lifting Chains are all used in the Utility market and are selected based on conditions, environment, frequency of use / inspection, budget and end user specification. The only restriction is where different Utility companies write specific requirements into their specifications. Even when this happens, contractors will normally go for a cheaper option when building new / refurbishing old works and when these stations are adopted by the Water company though from our experience they normally replace these chains to those according to their specification

Grade 50 316L Stainless Steel Pump Chains
The difference between A and A1 - A1 is just the normal chain link, where as A is a slightly bigger link that connects the oval link to the end of the chain link.
