Custom Magnetic Drive Pump Manufacturers

Sealless Magnetic Drive Pump Range for Corrosive Media

SYEELAI is a fluid handling manufacturing enterprise focused on mixing and transfer equipment. Under our Custom Magnetic Drive Pump program, we supply MP and MPH series magnetic drive pumps as part of the broader Chemical Pump range. Magnetic drive pumps use a magnetic coupling for non-contact torque transmission, eliminating the traditional mechanical shaft seal. The hermetically sealed, leak-proof design keeps the pumped fluid completely isolated from the atmosphere, which is essential for hazardous chemicals, volatile solvents, and expensive media.

We engineer these pumps around actual working conditions, not a fixed catalogue. Selection begins with media composition, temperature, required flow and head, then moves to wetted materials, motor power, piping layout, instrumentation and the control interface needed for safe operation. Our manufacturing base is in Yixing, Jiangsu, China.

Application Fit Across Chemical Process Lines

Magnetic drive pumps fit wherever a conventional glanded pump would create a leak risk or where maintenance around toxic media is expensive. Our MP and MPH series are suited to:

• Chemical transfer and circulation – acid, alkali, solvent and general process liquid movement.
• Electroplating and surface treatment – solution transfer and filter circulation where bath chemistry must remain stable.
• Water and wastewater treatment – chemical dosing, transfer and recirculation duties.
• Pharmaceutical and new energy utilities – handling clean or aggressive process media under controlled operating conditions.
• Operator safety – the absence of a shaft seal removes the main leak path for pressurized hazardous fluid.

When the pump is part of a larger skid, we coordinate it with our mixers, filters, valves and dosing accessories to match the total system requirement.

MP Series and MPH Series Selection

Hydraulic duty determines the series. Use the table below as the starting point; our engineering team confirms the selection against your actual piping and operating envelope.

For duties near the boundary between the two series, we can discuss the configuration rather than forcing a standard frame into an unsuitable operating point.

Wetted Materials and Critical Specifications We Evaluate

Corrosion resistance is the central selection criterion. We review media concentration, temperature, and whether the liquid contains solids or tends to crystallize.

• Flow rate and differential head at the normal and maximum operating point.
• Media name, concentration, pH and temperature range.
• Specific gravity and viscosity, since both affect absorbed motor power.
• Solids content, particle size, or crystallization tendency.
• Available NPSH, suction pressure and static suction lift.
• Electrical supply, motor voltage, frequency converter requirement and control signals.
• Installation environment, including outdoor exposure and hazardous area classification.

Configuration, Controls and Automation Integration

Sealless magnetic drive pumps simplify auxiliary systems because there is no gland water or seal flush piping to design, install and maintain. Connection orientation, motor position and baseplate arrangement can be matched to the existing line layout.

• Line integration – pump orientation and flange or threaded connections are defined from the piping arrangement.
• Motor and drive – standard or inverter-duty motor selection is based on absorbed power at the actual duty point.
• Control interface – we define the I/O points needed for start/stop, flow confirmation, and protection interlocks.
• System coordination – where the pump is supplied with a filtration or dosing package, the controls are coordinated with the accompanying valves, dampers and instruments.

Every proposal includes the electrical and process interface data needed by your automation contractor.

Quality Assurance and Acceptance

From raw material to finished pump, we operate a full-chain quality inspection system. Incoming materials are sampled and verified at the factory, production receives fixed-point patrol inspection, and finished products receive full-performance verification before release. Complete inspection data is retained for traceability.

• Raw material – sampling and verification on incoming materials.
• Production – fixed-point patrol inspection during manufacturing.
• Finished product – full-performance verification and retained inspection records.

Acceptance is based on the hydraulic duty agreed during selection, not on a generic catalogue rating. The as-built unit is checked against the flow, head, motor power and installation configuration defined in the proposal. We also maintain standardized industrial qualifications and an independent intellectual property system for fluid treatment equipment.

Project Information We Use to Configure Your Solution

• Pumped media and chemical composition, with concentration and pH.
• Operating temperature, density, viscosity and solids content.
• Required flow at normal and maximum head, including system resistance.
• Suction and discharge piping details: pipe size, length, static head and fittings.
• Electrical supply, voltage, frequency and control signal requirement.
• Process control method, such as local starting, remote DCS, or frequency converter.
• Installation area, ambient temperature and any area classification.
• Documentation language or standard required for your project.

Send these details with the inquiry; we return a configured proposal with the pump model, motor duty, materials, dimensions and support scope.

Installation, Service and Delivery Scope

SYEELAI supports the pump beyond supply. We design, install and commission non-standard chemical filtration systems and customized dosing devices, and our technical team provides remote diagnosis, on-site guidance and after-sales maintenance.

• 24/7 responsive service with remote diagnosis and on-site guidance.
• Exclusive service files and proactive tracking of equipment operation.
• Industrial-grade protective packaging for multi-scenario transport and loading/unloading.
• Synchronized logistics information for delivery updates.
• Maintenance planning and spare part lists prepared from the as-built configuration.

Product brochures, selection manuals and technical documents are available through our download channel. For international projects, we confirm packaging, documentation and shipping details before release.

Frequently Asked Questions

1. What is the difference between MP Series and MPH Series? The MP Series covers standard sealless transfer and circulation duties with leak-proof construction. The MPH Series uses an advanced magnetic coupling design for systems that must generate higher differential head. We confirm the correct series from the duty point and piping resistance.
2. Can magnetic drive pumps handle aggressive chemicals? Yes, when the wetted materials are matched to the media concentration and temperature. Our selection review includes chemical composition, pH, operating temperature and specific gravity before the model and material configuration are finalized.
3. What happens if a magnetic drive pump runs dry? Magnetic drive pumps rely on the pumped liquid for internal cooling and lubrication. Dry running can damage the internal bearing and magnetic coupling components. We define the minimum liquid level and control interlocks in the proposal to protect the pump.
4. How does the pump integrate with our control system? We provide motor data, connection arrangement and control interface recommendations. For automated lines, we include the start/stop, flow confirmation and protection interlock points that your DCS or PLC must provide.
5. What delivery and service support is included? Each pump is packaged with industrial-grade protective packaging suitable for global shipment. We provide installation and commissioning support for custom systems, remote diagnosis, on-site guidance and after-sales maintenance. Service documentation and spare parts lists are prepared from the as-built configuration.
