EBARA EVMS 1-90 Vertical Multistage Pumps

Built like a Katana

A Katana is a Japanese product, made with traditional know-how dating back to 300 a.C. It is manufactured with meticulous care and precision, embodying the mastery gained from years of experience. This philosophy guides EBARA's pump manufacturing. With 100 years of Japanese expertise, EBARA designs and produces pumps offering high performance, reliability, and cutting-edge mechanical components. EBARA's new vertical multistage pumps, the EVMS series, are manufactured to the highest quality standards, ensuring reliable operating performance through strict technical evaluation and control programs across the entire manufacturing process. EBARA listens to the market, and the unique EVMS design provides exceptional value through advanced solutions tailored to user needs.

Innovative Hydraulic Solutions

EBARA Pumps Europe offers innovative hydraulic solutions:

• Any motor, anywhere: Commercial motors can be fitted to all pump models without modifications, thanks to low pump axial thrust load.
• Long life of the motor bearing.
• High pump efficiency, classified with MEI > 0.7, representing the most efficient models.
• Patent Pending technology.

Smart Plug Solutions

• [Air Ventilation Plug]: For air ventilation.
• [Water Filling & Sensor Plug]: For water filling and sensor integration.
• [Commercial Sensor Fitting]: For commercial sensor applications.
• [Measurement Port]: For suction and discharge pressure or drain measurements.

Note: Two priming plugs are located on both sides of the motor brackets for EVMS32-90 models. A ventilation plug is integrated with one priming plug.

Stainless Steel Tie Rods

Tie rods are made from EN 1.4057 (AISI 431) as standard.

Piping Connection Options

Various pipe connections are available depending on application requirements. External dimensions can be adjusted for replacement of existing pumps in most cases.

Shaft Seal Solutions

Shaft seal materials include:

• B: Resin impregnated carbon graphite
• Q: Sintered silicon carbide
• Qg: Silicon carbide with carbon graphite

Carbon or graphite inclusions with silicon carbide can be used as a dry lubricant to reduce friction. Seals conform to EN12756 (formerly DIN 24960).

Easy Maintenance

• The cartridge shaft seal allows for plug-in replacement of the shaft seal without disassembling the motor bracket.
• The spacer coupling facilitates easy maintenance, avoiding the need to remove heavy motors over 5.5 kW.

EBARA Standard Motor Solutions

• IE3 efficiency for both 50 and 60 Hz* operation, compliant with IEC 60034-30 standard.
• ETM motors are available from 0.75 up to 11 kW for both 50 and 60 Hz**.
• PTC sensors (thermistors) are standard from 1.5 kW upwards for motor protection at 150°C.
• Unloosable screws and sealing are standard for terminal box fixing from 0.75 kW upwards.
• Stable inverter mounting on fan covers made of pressed steel.

* IE3 for 60Hz is dependent on motor size and voltage.
** All other sizes, including single-phase motors, are available with commercial IEC standard motors.

Solve Axial Thrust Load

Pump axial thrust load arises from the static pressure imbalance between the front and back shrouds of an impeller, which reduces motor bearing life. Traditional methods to manage axial thrust include increasing motor bearing size or adding extra bearings to the pump bracket, often leading to complicated mechanical structures. EBARA's newly designed "Shurricane" impeller reduces pump axial thrust load with high pump efficiency through its innovative hydraulic design. This allows EVMS pumps to accept standard commercial motors without modifications, improving motor bearing maintenance cycles.

[Diagram Description]: A diagram illustrates axial thrust. On the left, the "Shurricane impeller" shows balanced forces indicated by arrows, suggesting reduced axial load. On the right, a "Normal impeller" shows unbalanced forces, indicating higher axial load.

Performance Range

Performance curves illustrate the relationship between head (H) and flow rate (Q) for various EVMS pump models (1, 3, 5, 10, 15, 20, 32, 45, 64, 90) at 50Hz and 60Hz frequencies. The graphs display pressure (P) in MPa, head (H) in meters and feet, and flow rate (Q) in liters per minute and cubic meters per hour.
