MOYNO

Moyno is a brand historically associated with the development and manufacture of progressive cavity pumps, also known as helical rotor pumps or eccentric screw pumps. The original Moyno pump was invented by René Moineau in the 1930s, and the brand has since become a reference name for this positive displacement pump technology. Moyno progressive cavity pumps operate by means of a single helical rotor turning inside a double helical stator, creating sealed cavities that move axially as the rotor turns. This geometry produces a steady, low-pulsation flow that is suitable for transferring fluids with varying viscosities, including those containing solids or shear-sensitive media. The product families supplied by 3G Electric include bare shaft wobble stator PC pumps, motorized wobble stator PC pumps with direct drive AC motors, and repair kits for specific Moyno pump models. The wobble stator design allows the stator to move slightly during operation, which can help manage the effects of abrasive or viscous fluids. Bare shaft pumps are supplied without a motor, allowing the user to select a drive that matches the required flow and pressure. Motorized units come with a direct drive AC motor, typically single-phase, and are ready for installation in water transfer and similar applications. Construction materials for the pumps include cast iron housings, Buna-N stators, stainless steel rotors, and mechanical seals with carbon faces. These materials are selected for compatibility with water, wastewater, and general process fluids. The pumps are available with threaded inlet connections, such as 3/4 inch FNPT, and are part of the 300 Series. Maximum flow rates and viscosity limits vary by model; for example, some bare shaft units are rated for flow rates around 4.8 gallons per minute at specified conditions. Repair kits are available for several Moyno models, including 33201, 33259, 33301, 33359, 34401, 34459, 35601, and 35651. These kits include components such as stators, flexible joints, and seals, and are identified by manufacturer part numbers like 3119027000, 3119029000, 3119031000, 3119033000, and 3119123000. The kits are intended for servicing pumps in industrial applications, including wastewater handling. 3G Electric supplies Moyno pumps and repair kits as part of its industrial equipment catalog. The company serves plant engineers, maintenance managers, and procurement specialists who require progressive cavity pumps for fluid transfer and process duties. 3G Electric provides access to technical specifications, model compatibility information, and quotation support for Moyno products. The product range includes both new pumps and aftermarket repair kits, allowing users to maintain existing installations. For motorized units, 3G Electric also carries related motors, such as SEW-EURODRIVE models, which may be used as replacements or for custom drive arrangements. The focus is on supplying components that match the original equipment specifications, with attention to materials of construction and dimensional compatibility. This approach supports maintenance and repair activities in industries such as water treatment, wastewater processing, and general manufacturing. 3G Electric operates globally, shipping Moyno products to customers worldwide. The catalog includes detailed part numbers, model numbers, and technical data to assist with identification and selection. For applications requiring progressive cavity pumps, 3G Electric can provide information on available models, repair kits, and associated components. The company does not manufacture Moyno products but distributes them as part of its broader industrial equipment offering. Customers can request quotes and technical support through 3G Electric's standard channels.

Frequently asked questions

Common questions about MOYNO from 3G Electric.

What is the difference between a bare shaft and a motorized Moyno progressive cavity pump?

A bare shaft Moyno progressive cavity pump is supplied without a motor or drive, allowing the user to select and mount a drive that matches the required flow rate, pressure, and control method. A motorized Moyno pump includes a direct drive AC motor, typically single-phase, and is ready for connection to power and piping. Motorized units are often used in water transfer applications where a standard motor speed is suitable. Bare shaft pumps offer flexibility for custom installations or when a specific motor type or speed is needed. Both types use the same wobble stator pumping principle and are available in similar materials of construction.

What models are covered by Moyno repair kit 30EK58?

Moyno repair kit 30EK58 is compatible with Moyno pump models 33201 and 33259. It includes a flexible joint as a key component. The kit is identified by manufacturer part number 3119027000 and is used for servicing pumps in applications such as wastewater handling. This kit is one of several repair kits available for different Moyno pump series. Always verify the specific pump model and part number before ordering to ensure compatibility.

What materials are used in Moyno wobble stator PC pumps?

Moyno wobble stator PC pumps supplied by 3G Electric typically feature cast iron housings, Buna-N stators, and stainless steel rotors. The mechanical seal has a carbon face. These materials are selected for compatibility with water, wastewater, and various process fluids. Buna-N provides resistance to many oils and water-based fluids, while stainless steel offers corrosion resistance for the rotor. Cast iron provides structural strength for the housing. The specific materials may vary by model, so consult the individual product specifications for exact details.

What is the maximum flow rate for Moyno 300 Series bare shaft pumps?

Moyno 300 Series bare shaft wobble stator PC pumps have varying maximum flow rates depending on the model. For example, one model is rated for a maximum flow of 4.8 gallons per minute, with a flow of 4.1 gallons per minute at 30 psi. Flow rates are influenced by pump size, speed, and viscosity of the fluid. The 300 Series includes multiple models with different displacements. For precise flow data, refer to the technical specifications for the specific model number. 3G Electric can provide detailed performance curves and selection assistance.

Which Moyno pump models are compatible with repair kit 30EK61?

Moyno repair kit 30EK61 is designed for Moyno pump model 35601. It includes a stator and is also used for flex joint and seal replacement. The kit is identified by manufacturer part number 3119033000 and is compatible with part number 30EK53. This kit is part of a series of repair kits for different Moyno models. It is used to replace worn components and restore pump performance. Confirm the pump model and part number before ordering.

Can 3G Electric supply Moyno pumps with alternative motors?

3G Electric supplies Moyno motorized progressive cavity pumps with direct drive AC motors as standard. The catalog also includes motors from other manufacturers, such as SEW-EURODRIVE, which may be used for replacement or custom drive arrangements. For applications requiring a specific motor type, speed, or enclosure, 3G Electric can provide information on available options. The bare shaft pump models allow users to mount their own motor or drive. Consult 3G Electric for assistance with motor selection and compatibility.
