Pump repairability can be inhibited by the simplest things. The use of glues or epoxy may be technically tempting to achieve a water-tight cable entry. However, from a service and repairability point of view, this makes subsequent repairs more prone to water ingress, especially when repairs are performed without necessarily having the clean environment that is required to get a suitably water-tight entry. Other submersible pump best practices, such as “never reuse O-rings” are easily followed with the availability of repair kits, including all the necessary O-rings. Repair kits ensure that all necessary parts that need changing are actually changed. Otherwise, the technicians servicing the pump might find themselves forced to reuse an old O-ring, which in a submersible electric pump can lead to premature failure. But repairability is more than that. Pumps that are designed with a readjustment possibility for wear, recovering performance to as-good-as-new, are desirable from a sustainability point of view. This is required as they postpone the exchange of wear parts to the absolute last moment. Repairs can be more reliably executed if essential service moments are made more secure from a service standpoint. For example, a crucial part of a submersible dewatering pump is the mechanical seal. The mechanical seal solves the technical challenge of making the combination of a rotating shaft, with a hole in the wall of a part, water-tight. Conventional mechanical seals consist of many parts that need to be fitted in the right order, in a relatively clean environment which is next to impossible to find in a mining job site. Recently designed submersible pumps typically use cartridge-type mechanical seals, where the entire seal system is changed as one unit. This avoids the pitfalls of wrong assembly and contamination of critical sealing systems.
