Effective & Reliable
Protection for Pumps

Pumps are often exposed to hazardous conditions and situations that can cause severe damage to the pump. Littelfuse SymCom PumpSaver® products will protect and disable a pump in these situations. PumpSaver® offers a wide variety of controls for both single phase and three phase applications. Among these control options are, intrinsically safe and alternating relays, pump controllers, liquid level controls and seal leak detectors, and power monitors which are all excellent choices for your
pump protection needs.


Intrinsically Safe Relays

Applying electronic controls in hazardous environments can be difficult. Fortunately, Littelfuse SymCom intrinsically safe relays and pump controllers are specifically designed to interface between hazardous and non-hazardous areas. We provide several models of intrinsically safe relays and controllers offering distinct output relay configurations for a variety of systems.

Alternating Relays

Alternating relays are designed to balance the run time between two independent loads, typical in many pumping and compressor applications. By balancing the run times, redundant equipment is equally exercised to provide greater system reliability.

Pump Controller Relays

Multiple-pump applications often require balanced run times and redundancy. Littelfuse SymCom provides pump controllers (both intrinsically safe and non-IS) that are designed to handle multiple pump applications.

Liquid Level Controls /
Seal Leak Detectors

Littelfuse SymCom liquid level control relays are used to control conductive liquid pumping operations using either floats or conductance probes. They can be used in pump-up or pump-down applications.

Our seal leak and leak/temp relays provide protection against seal leaks and over-temperature by monitoring sensors within the pumps and providing early warning or disabling the pumps.

Enhanced Power Monitors

Many pumping applications require advanced power monitoring and control. Littelfuse SymCom enhanced power monitors provide all of the protection and features included with an enhanced overload relay, and are designed specifically to support low horsepower and/or low speed motor applications. This family of enhanced power monitors provides optimal protection for any type of motor or pump.
