MEW series 60Hz
PDF datasheet mirror for MEW series 60Hz (Rovatti Pumps). Verify with OEM before design.
Summary
Product Identification
Rovatti MEW series close coupled electric pumps, 60Hz. Document reference: CBMW60-16-IGFDE-R1.
General Description
These are single-stage close coupled electric pumps with a keyed impeller on the motor shaft, axial inlet, and scroll outlet. They are designed for diverse applications, offering robust construction, easy installation, low running costs, safe operation, and reduced overall dimensions.
Pump performances are referenced to cold water (20 °C) at atmospheric pressure (1 bar) according to ISO 9906 - Annex A norms. Catalogue performances refer to liquids with a density of 1000 kg/m³ and kinematic viscosity not higher than 1 mm²/s. Tolerances are ISO 9906 Grade 3B.
Performance Overview
- Capacity: up to 180 m³/h
- Head: up to 60 m
- Power: up to 22 kW
Operating Limits
- Max. solids contents: 40 g/m³
- Max. water temperature: 90 °C
- Max. running time with Q=0: 2 min
- Max. operating pressure: 10 bar
- Max. suction pressure: 4 bar

Mechanical / Hydraulic Data
Detailed overall dimensions and weight for each model (MEW3T/32 to MEW30T/80) are available. Performance curves (Head and NPSH) at 3500 min⁻¹ for various flow rates (m³/h, l/s, l/min) are provided for each model.
See the official PDF for exact tabulated values for dimensions, weight, and performance curves.
Twinner System®
This system facilitates maintenance of the stuffing-box packing:
- A) Flange: Made of two stainless steel halves, allowing for simple extraction to facilitate replacing the stuffing-box packing.
- B) Stuffing-box packing: Easy to adjust and long-term functioning, operating on a stainless steel chromium-coated bush.
- C) Screws: Stainless steel screws enable easy disassembling even after many hours of operation, allowing work on the gland packing box without removing the shaft support.
