• Single, end suction type with radially split, top center-line discharge, self-venting casing.
• Designed, manufactured, and inspected to exacting standards.

Operating limits

The pressure/temperature chart for Series 4030 pumps is provided for clear, clean water. Values may change with other liquids.

Maximum Working Pressure/Temperature (Standard Seal):

• Cast Iron (ANSI-125 flanges):
  • 0 °F (-18 °C) to 50 °F (10 °C): 300 psig (20.00 bar)
  • 100 °F (38 °C): 250 psig (17.24 bar)
  • 150 °F (66 °C): 200 psig (13.79 bar)
  • 200 °F (93 °C): 150 psig (10.34 bar)
  • 250 °F (121 °C): 50 psig (3.45 bar)
• Ductile Iron (ANSI-250 flanges):
  • 0 °F (-18 °C) to 50 °F (10 °C): 300 psig (20.00 bar)
  • 100 °F (38 °C): 250 psig (17.24 bar)
  • 150 °F (66 °C): 200 psig (13.79 bar)
  • 200 °F (93 °C): 150 psig (10.34 bar)
  • 250 °F (121 °C): 50 psig (3.45 bar)

Hydrostatic Test Pressure:

• 150% maximum working pressure at ambient temperature.

Feed water

• Values are based on clear, clean water.
• Mechanical seal options are available for specific applications:
  • Antimony loaded carbon for hot fluids.
  • Silicon carbide faces for glycols above 30% concentration by weight.

Electrical

• The pump requires connection to a motor, with specifications (hp, Hz, phase, Volts, rpm, enclosure, efficiency) to be determined by the project plans and specifications.

Mechanical / hydraulic

Key Features:

• Casing: Radially-split, base supported, ANSI style centerline discharge, self-venting to eliminate vapor lock, ANSI flanged.
• Design: Back pull out design allows removal of bearing assembly and impeller without disturbing pipe connections.
• Baseplate: One-piece, heavy fabricated steel, rigidly constructed to ANSI/HI 1.3.5 rigidity standards for grouting or freestanding.
• Coupling: Flexible coupling with OSHA guard.
• Bearings: Two anti-friction, pre-lubricated and sealed ball bearings, designed for minimum maintenance.
• Seal: Single spring mechanical seal with silicon carbide seat, designed for leak-proof operation.
• Shaft: Stainless steel shaft sleeve.
• Impeller: Dynamically balanced, cast bronze or iron.
• Gasket: Confined, non-asbestos casing gasket.
• Connections: Drilled and tapped connections for gauges and drain.

Construction Materials:

• Housing: Cast iron, bronze-fitted construction (all iron and ductile iron construction available).
• Impeller: Cast bronze or iron.
• Shaft Sleeve: Stainless steel.
• Mechanical Seal Seat: Silicon carbide.
• Gasket: Non-asbestos.
• Baseplate: Heavy fabricated steel.
