G 系列内齿轮泵 通用带支架齿轮泵——夹套型与非夹套型

1Pressure Relief Valve

Protects pump and seals in the event of excessive pressure.

1Jacketed Pressure Relief Valve Option

• Ensures that the valve is at appropriate operating temperature when it needs to open
• Jacketed valve recommended with jacketed head
• Available on G2-55, G2-69, G2-82, G2-133, and G2-222 cast iron models

2Head Screws

Securely fastens head to case.

3Head

Top end of pump that supports idler gear and one side of the rotor shaft assembly. Contains ports and mounting point for pressure relief valve. Heavy-duty construction for rugged use and long life.

3Jacketed Head Option

• Large, jacketed surface area
• Maintains product and process temperature
• Keeps liquid at appropriate viscosity to maintain proper lubrication of the bushings/pin
• Available on G2-55, G2-69, G2-82, G2-133, and G2-222 cast iron models

4Head Gasket

Seals surface between case and head.

5Case

Central body casing of pump with inlet and outlet ports. Case can be rotated for multiple inlet/outlet and flow orientation.

5Jacketed Case Option

• Adding jacketed case ensures the highest level of temperature and process control
• Available on the G2-55 and G2-133 case iron sizes only

6Idler Gear

Connected to and driven by the rotor/shaft assembly.

7Bracket Gasket

Seals surface between case and bracket.

8Rotor/Shaft Assembly

Consists of shaft and rotor gear, and drives idler gear. Can rotate in either direction to reverse pumping direction as required.

9Bracket

Pump frame with easy access mounting holes for bolting down pump at installation site. Durable construction for minimal vibration and long life.

9Jacketed Bracket Option

• Standard and required option when choosing a jacketed design
• Provides temperature control in the bushing area that radiates to the low velocity area behind the rotor, a typically cold spot in the pump
• Keeps material in the seal area warm, which prevents product from hardening and damaging the seal upon startup
• Available on G2-55, G2-69, G2-82, G2-133, and G2-222 cast iron models

10Bracket Screws

Securely attaches case to bracket.

11Packing

Low cost substitute for seals; minimizes/controls leakage of rotor/shaft assembly.

12Mechanical Seal

Provides secure sealing around rotor/shaft assembly.

13Seal/Packing Gland

Securely houses seal or packing around rotor shaft.

14Gland Screws

Firmly attaches seal gland to bracket.

15Bearing Housing Assembly

Allows smooth, accurate rotation of rotor shaft assembly. Enlarged bearing housing provides easy access to shaft seal and single-point end-clearance adjustment for ease of maintenance and adjustability.
