‘With proper care and maintenance, your pump should provide years of service....’ is a common statement in Owner’s Manuals, but the specific practices are seldom described.
For Pumptec pumps, there are a few simple practices to follow to keep the pumps in proper working order.
1) Pumptec pumps are intended to pump ambient temperature clear water and water-based solutions in the 7 pH range (Standard chemicals). Solutions that do not fit this description may be able to be pumped, with additional care and consideration (Non-standard chemicals). Under no circumstances is it recommended to pump volatile chemicals like gasoline, acetone, etc... These high VOC chemicals are prohibited.
2) After use with a non-standard chemical, the pump should be flushed with clear water and left with only clear water inside until the next use. Chemicals left inside the pump can corrode and damage internal parts and surfaces resulting in rapid wear.
3) Hot liquids, greater than 120 F, can cause damage in the pump and erosion failure. Hot water is unstable and can flash to gas during the pumping process causing cavitation which will erode and pit the pump body parts. If hot water must be used, it needs to be pressurized either by placing the tank above the pump (up to 130F) or by the use of a booster pump (beyond 130F).
