Mechanical Seals, Integral Pressure Lubrication:

• These models use mechanical seals on the rotor shafts and drive shaft.
• Flanged port fittings and water-cooled drive shaft seals are standard.
• An integral pressure lubrication system with a water-cooled heat exchanger is included.
• Cooling coils in the end covers are part of this configuration (excluding optional motor mounting flange versions).

Slinger Seals, Integral Pressure Lubrication:

• The models utilize a mechanical drive shaft seal combined with a non-contacting, non-wearing slinger seal on the rotor shafts.
• This configuration includes water-cooled drive shaft seals and flanged port fittings.
• It has an integral pressure lubrication system with a water-cooled heat exchanger, though cooling coils are not included.

Low Mechanical Noise:

• Designed to operate at low noise levels, with an output of 82 dB(A) or less at blank-off. This measurement excludes motor and background noise, ensuring quieter operation in industrial environments.

Special Materials:

• Standard construction materials include cast iron housing, ductile iron rotors and shafts, and end plates with port fittings.
• Special materials (available for select models) include stainless steel, carbon steel, or additional coatings like Bi-Protec® (Nickel/Armoloy® special coating) for added durability.

Optional Motor Mounting Flanges:

• These models come with optional flange adapters for mounting NEMA C-face motors (up to 75 HP) or IEC D-flange motors (up to 55 kW).
• This option eliminates the need for a separate base-mounted assembly and coupling guard, simplifying installation and reducing space requirements.

Metric Availability:

• These boosters are available with metric drive shafts and process connections for compatibility with international standards.

Special Testing:

• The boosters undergo a variety of specialized tests, including ASME PTC-9 testing, hydrostatic testing up to 150 PSIG (10.35 bar g), and pressure gas testing up to 100 PSIG (6.9 bar g).
• Seal leakage testing ensures the reliability and tightness of the system.
