What Makes a Reliable Chemical Transfer Pump?

A chemical transfer pump must be capable of the safe transfer of chemicals within a system. The key word here is safe. Not all pumps are capable of handling the harsh chemicals involved in many applications. For tough environments such as chemical manufacturing, steel processing, water and wastewater treatment, and mining, pumps must offer proven design and reliable construction that can be counted on to deliver when it counts.

Specifying pumps designed with sealless technology delivers the reliability needed for these applications. The sealless design eliminates leaks and drastically reduces pump maintenance. These qualities, combined with other unique advantages, make a chemical transfer pump ideal for heavy-duty solutions. For the most reliable chemical transfer pump, look for the following crucial features.

Top Qualities of a Chemical Transfer Pump

Sealless mag-drive technology

Mechanical seals inevitably break down. When they do, leaks occur. A leak can cause anything from a minor inconvenience to a major disaster. But these issues can be avoided with a sealless chemical transfer pump. The sealless mag-drive technology eliminates the cost, down-time, and potential hazards that leaks create. Because there is no seal, there are no leaks.

Tip: Look for a chemical transfer pump that features powerful neodymium magnets that deliver dependable, leak-free operation.

Robust construction

Myriad applications require the management of harsh substances. A reliable chemical transfer pump can withstand the chemical exposure involved in these operations. Built to handle these environments, a chemical transfer pump delivers reliable performance even under these tough conditions.

Tip: Reliable pumps can absorb loads from hydraulic and other forces and feature wall thickness that ensures the integrity of the pump housing.


A reliable chemical transfer pump is available in a variety of configurations, to suit the needs of a full range of applications. Self-priming, multi-stage, ANSI dimensional, and vertical pumps offer designs for each unique requirement. With so many options, it is easy to choose a chemical transfer pump that is ideal for each specific application.

Tip: Use a professional pump selector to guide your pump spec and find the appropriate chemical transfer pump for your application.

Run-dry capability

At times, human error or system malfunction may result in a run-dry situation. For some pumps, this can prove disastrous. The pump may burn out and entire systems may shut down due to the pump failure. For a reliable chemical transfer pump, a run-dry scenario is not a problem. The pump can run dry without damage, in some cases for up to several hours.

Tip: This quality is particularly crucial for settings where pumps operate without direct supervision.

Solid warranty

A heavy-duty pump should come with heavy-duty assurance. A reliable chemical transfer pump is backed by a manufacturer’s warranty. The manufacturer stands confidently behind their product, offering multi-year warranties for robust pumps.

Tip: Top manufacturers also offer support and troubleshooting resources to deliver complete customer care.

Dependable brand

A reliable chemical transfer pump is stamped with a reliable name. It is produced by an established manufacturer that has a track record of success. The brand is a trusted name, known for developing reliable products and delivering excellent service.
