Immersible pumps have a motor built to be able to continue running in an uncommon event where it may become submerged, but they are not designed to be submerged on a daily basis. These motors are designed to operate in a dry environment and can be retrofitted where a vertical solid shaft motor was previously used. For pumps designed for submersible conditions,
Pump Solutions #1 Corp carries the leading brands in immersible pumps, including AMT. Immersible pumps are designed for pumping coolants, cutting oils, or lubrication fluids for multiple applications.
Immersible and submersible pumps are built for different applications. Submersible pumps are built to be very heavy-duty, but are expensive. Immersible pumps are cost-effective, but are built for lighter applications.
Instead of the oil reservoir found in submersible pumps, immersible pumps have a drive endplate packed with moisture-resistant grease. Compared to submersible pumps, immersible pumps are generally most cost effective to maintain, fix, purchase, and operate.
When choosing a pump, it’s important to take into consideration the conditions it will be operating in. If the pump has the possiblitiy of being submerged, an immersible pump may be the right choice. However, if the pump will be continuously submerged, a submersible pump is probably the right choice.
