Design Features
- Axially Split Casing - For extreme ease of maintenance.
- Dual Volute Design - Balances hydraulic radial thrust at each stage for extended seal/bearing life.
- Integral Compact Crossovers - Minimize flow losses, maximize efficiency.
- Heavy Duty Single Row Bolting - Prevents distortion and chance of interstage leakage.
- Precision Impellers - Individually balanced for smooth operation.
- Opposed Impeller Arrangement - Provides permanent axial hydraulic balance.
- API-610/ISO 13709 Compliance is Available
Low Vibration / Smooth Performance
- Individual impellers and complete rotor assembly dynamically balanced.
- Shrink fit of impellers to shaft assures precise balancing of rotating assembly.
- Precision cast impellers have equal volumes between vanes for reduced pressure pulsations.
Serviceability
- Cartridge type mechanical seals for ease of assembly, proper installation.
- Single row bolting with stud nuts located on upper half for easy accessibility.
Split stage pieces and center case bushing can be removed for inspection of wear surfaces without disassembling rotor assembly.
Rotating Assembly
Entire rotating assembly can be removed for maintenance
without disturbing suction / discharge piping. Single row bolting simplifies disassembly / reassembly.Designed for API-610 11th Edition / ISO 13709 Services
- Casing, nozzles and baseplate meet API-610 nozzle load requirements.
- Impellers are shrink fit to shaft and independently secured against axial movement.
- Seal chambers meet dimensional requirements of API-610 and can be fitted with single, double or tandem cartridge mechanical seals.
- Steel bearing frames standard for maximum structural integrity.
- Impellers and rotating equipment element dynamically balanced to API-610 / ISO 13709 requirements.
- Separation margins between operating speeds and critical speeds meet or exceed API-610 / ISO 13709 requirements.
Design/Analysis Capabilities
Casing pressure capability and structural design developed and refined using advanced finite element analysis. Goulds engineering staff is fully equipped to perform the rotor lateral response analyses and residual unbalance checks necessary to assure stable operation and low vibration levels.
Thermal transient analysis using finite element models used to determine allowable casing temperature rise and assure mechanical reliability. Hydraulic designs developed using dynamic flow models assure stable performance with consistent, high efficiency levels.Bearing Arrangements
Oil lubricated ball radial and duplex thrust bearings are standard on the Model 3600. Ring oil lubricated sleeve radial and ball thrust or pressure lubricated sleeve radial and tilting pad thrust bearings can be furnished to meet customer or operating requirements.
Double Suction First Stage Impeller
Available on 4-inch and larger discharge size pumps for services where NPSHA is limited.
Shaft Sealing and Seal Chambers
The Model 3600 can be sealed either by soft packing or mechanical seals. Seal chambers meet API-610 / ISO 13709 dimensional requirements, and accept a wide range of cartridge type mechanical seals, including API 682 / ISO 21049. Both seal chambers and stuffing boxes can be furnished with cooling jackets.
Destaging and Instrumentation
Goulds Model 3600 can be supplied with one or more blank stages to meet existing head conditions, and allow for future increases. The shaft is protected by a sleeve to maintain the impeller fit. A by-pass cylinder assures smooth, even flow to the next impeller.
The 3600 can be furnished with instrumentation options to measure vibration and temperature. RTD’s or thermocouples can be furnished to measure bearing temperatures and to monitor temperature rise in the casing. Bearing housing vibration can be monitored on pumps furnished with ball bearings. Pumps supplied with sleeve bearings can be furnished with non-contacting vibration probes to measure actual rotor vibration.
