Grundfos MTA Immersible Centrifugal Pump (Machine Tool Pump)
Product Overview
The Grundfos MTA series consists of single-stage immersible pumps designed specifically for the machine tool industry. Primarily used in filtration systems, they efficiently transport liquids containing chips, fibers, and abrasive particles to the filtration unit.
Key Features
1. High-Efficiency Handling Capability
Semi-open Impeller Design: Allows passage of debris up to 10mm in size; suitable for pumping liquids containing debris, fibers, and abrasive particles.
Strainer-free Design: Unlike the MTR/SPK series, the MTA pump requires no inlet strainer and can directly handle liquids containing particles.
2. Structural Characteristics
Seal-less Design: Features a seal-less structure with no shaft seals or other wearing parts, ensuring maintenance-free operation.
Modular Construction: Composed of core components such as the pump housing, impeller, and shaft with rotor; simple and reliable structure.
Material Selection: Pump housing made of cast iron; impeller made of PAA GF50 or bronze for wear resistance.
3. Installation Flexibility
Immersion-style Installation: Designed for vertical mounting on top of a tank, with pump components submerged in the liquid.
Selectable Inlet/Outlet Configuration: Offers both top-inlet and bottom-inlet configurations to suit various installation requirements.
Compact Design: Installation lengths range from 150mm to 350mm, saving space.
4. Performance Parameters
Flow Rate Range: 30–200 L/min (50Hz) or 35–250 L/min (60Hz).
Head Range: Up to 11.1m (50Hz) or 15.6m (60Hz).
Temperature Range: Standard version suitable for liquids at 0–60°C; special versions available upon request.
5. Special Models
MTA-H High-Pressure Series: Offers high-head versions (MTA 20H/40H/70H/100H) with heads reaching up to 19.1m (60Hz).
Wide Range of Specifications: Nine hydraulic models available (from MTA 30 to MTA 200) to meet diverse flow rate requirements.
6. Motor Configuration
High-efficiency motor: Equipped with an IE3 efficiency-class motor; power ratings range from 82W to 815W.
Multiple voltage options: Supports various voltage configurations, such as 3×200V and 3×220-240V/380-415V.
Protection rating: IP54 motor protection rating, suitable for industrial environments.
Typical Applications
Machine tool coolant circulation systems
Transfer of fluids containing chips/swarf
Industrial filtration systems
Cutting fluid recovery and processing
Grinding machine cooling systems
With their robust design and ability to handle fluids containing particulates, MTA pumps are ideally suited for the demanding operating environments of the machine tool industry, effectively reducing maintenance requirements and enhancing system reliability.
