SEEPEX

SEEPEX progressive cavity pumps supplied by 3G Electric include rotors made from stainless steel or titanium, and housings constructed from stainless steel. These material options provide corrosion resistance for handling aggressive chemicals or fluids in sanitary applications. The choice between stainless steel and titanium rotors depends on the fluid's chemical composition and temperature; titanium offers higher resistance to chlorides and acidic environments. Seal materials, such as Viton, are selected for compatibility with specific media. Always consult the pump's material data sheet for full compatibility with your process fluid.

The SEEPEX metering pumps stocked by 3G Electric are configured for 115V AC single-phase power, with motor ratings of 1/2 hp or 3/4 hp depending on the model. Some cavity pump models are available at 120V AC single-phase. These voltage options are suitable for standard industrial electrical supplies in many regions. For other voltage requirements, such as 230V AC or three-phase, custom configurations may be available through special order. Verify the nameplate voltage and phase requirements before installation to ensure compatibility with your facility's electrical system.

SEEPEX offers both standard stators and wobble stator designs in their progressive cavity pumps. A standard stator has a fixed geometry that provides consistent compression along the pump length, suitable for general fluid transfer and metering. The wobble stator, also known as a flexible stator, allows the stator to move slightly, reducing wear when handling abrasive or solids-laden fluids. This design extends pump life in demanding applications like sludge handling or mining slurries. The choice depends on the fluid's abrasiveness and the required service interval. 3G Electric stocks both types; check the product specifications for stator type.

The SEEPEX pumps available from 3G Electric commonly feature Viton (FKM) seal material. Viton is a fluoroelastomer that offers good chemical resistance to oils, fuels, acids, and many solvents, with a temperature range typically from -20°C to +200°C. This seal material is suitable for a wide range of industrial fluids, including hydrocarbons and corrosive chemicals. For applications requiring different seal materials, such as EPDM or PTFE, consult 3G Electric for availability or custom options. Always verify seal compatibility with your specific fluid to prevent leakage or premature failure.

Yes, SEEPEX progressive cavity pumps are designed to handle fluids containing solid particles, up to a certain size depending on the pump model and stator geometry. The positive displacement action allows solids to pass through the pump without damaging the rotor or stator, provided the particle size does not exceed the pump's clearance limits. For abrasive solids, a wobble stator design is recommended to reduce wear. The maximum particle size is typically specified in the pump's technical data; for example, some models can handle particles up to 30 mm. Consult the product manual for your specific SEEPEX pump to determine the allowable solid content.

The flow rate of SEEPEX metering pumps depends on the pump size, rotor/stator geometry, and motor speed. For the models stocked by 3G Electric, flow rates typically range from a few liters per hour up to several cubic meters per hour, depending on the specific model and operating conditions. For example, a 1/2 hp pump with a titanium rotor may deliver flow rates in the range of 0.5 to 5 m³/h at nominal speed. Precise flow rates are proportional to rotational speed, allowing accurate metering. Refer to the pump's performance curve or data sheet for exact flow rates at your required pressure and viscosity.
