Function

GRUNDFOS MTSE Variable-Speed Screw-Spindle Immersion Centrifugal Pump (Cutting Oil Pump)

The MTSE variable-speed screw pump is designed for coolant and cutting oil delivery in metalworking centers, featuring the following core capabilities:

1. High-Efficiency Variable-Speed Drive

Supports 50/60Hz variable-speed regulation to meet varying flow and pressure requirements
Equipped with an IE5 high-efficiency motor for optimized energy consumption
Voltage range: 3×220-480V (50Hz) / 3×220-277V (60Hz), compatible with global power grids

2. Precision Hydraulic Design

Tool steel spindle (1.2379 material): Specially hardened for excellent wear resistance
Silicon carbide mechanical seal: Suitable for high-pressure conditions (up to 100 bar) with long service life
Modular screw angle options: Various specifications (R34–R76) available to precisely match flow requirements

3. Flexible Installation and Connection

Multiple installation methods:
Immersion type (T-model): Axial inlet, directly immersed in the fluid
Dry installation (D/H-model): SAE flange connection, supports side or horizontal mounting
Piping connections:
Outlet options: G3/4" thread or SAE flange (MTS 25 model)
Inlet options: G1/G1½" thread or SAE flange (MTS 32 model)

4. Low Noise and Long Service Life

Noise level ≤78 dB(A): Significantly lower than comparable lobe pumps and centrifugal pumps
Wear-resistant cast iron housing (EN GJL-250): Resistant to corrosion and mechanical impact
External main bearing design: Reduces internal wear and extends maintenance intervals

5. Safety and Compatibility

External safety valve required: Protects the system against overload (not included as standard; must be selected separately)
Media compatibility:
Emulsions (oil content 2–20%)
Cutting oils (containing EP additives)
Inorganic solutions
Filtration requirements: Compliant with ISO 4406 cleanliness standards (recommended filter mesh size ≤65 μm)

6. Intelligent Control Integration

Optional electronic proportional safety valve (E-type) available, supporting pressure control via 0–10V analog signals
Built-in PTC thermistor (for motors ≥3 kW) providing overheat protection

Typical Application Scenarios:

High-pressure cooling systems for CNC machine tools
Centralized fluid supply for automated machining lines
Lubricant circulation for grinding machines and deep-hole drilling equipment
