Neptuno Pumps® - Axial Split Case
Multistage Pump (HA) poster
Axial Split Case Multistage Pumps (HA)
Split Stage Center Bushing
• Allow dynamic balancing of
assembled rotating element.
• Can be removed for
inspection of wear surfaces
without disassembling rotor
assembly
Hydraulic Crossover
• Minimum friction loss,
maximum efficiency.
• Provides permanent axial
hydraulic balance.
Pumpshaft
• Fully machined and
sized for application
thrust and torque
• Different engineered
alloys for aggressive
applications
Dual Volute Heavy-Duty Casing
• Smoothly transitions fluid
• Assures radial balance for
minimum shaft deflection.
• Discharge connections are in
the lower half casing, allowing
removal of upper half casing
for ease on-site inspection
and/or reparation.
Double Suction First Stage Impeller
• Fully investment casted to
provide smooth passageways
for low-loss fluid flow
• Precisely trimmed and
balanced to reduce vibration
and wear
• Available for low NPSH
service requirements.
Oil-Lubricated Bearing Assembly
• Engineered bearing
arrangements to meet
specified operating
requirements.
• Withstands the total
hydraulic thrust
• Easily replaceable radial
bearing
Single Row Bolting
• All nuts located on top for
ease of maintenance.
Opposed Impeller Arrangement
• Provides permanent axial
hydraulic balance.
IMPELLER ARRANGEMENT
Double suction + 2 impellers in parallel
Double suction + 4 back-to-back impellers.
Automatization, Control & Monitoring
Pump Process Control Software
AUTOMATIZATION, cONTROL & MONITORING
Reduce system operation and maintenance costs while increasing process accuracy and protection. The software provides multiple pump control and protection, as well as system monitoring and protection.
- Power rating: 0.75 to 2000 kW (1 to 2500 hp)
- Power supply: 200-240 V, 380-480 V, 575 V and 690 V
- Human Machine Interface (HMI) with backlight,
graphic display and soft-keys, and real time clock - Reduced System Component Cost
- Improved System Reliability
- Reduce Maintenance Costs
- Eliminate Costly Control Panels
- Reduce System Energy Requirements
- Reduce Overall Installation Costs
PUMP PROCESS CONTROL SOFTWARE
Pump Genius software monitors system pressure or flow and references low / high set point and run time requirements. The lead and lag pumps are cycled on and off based on motor run times.
- Starting/stoping motors are selected based on run time - motor with least amount of run time
- All pumps are dynamically alternated based on run times and system set point requirements
- System, motor, drive faults are monitored and alarmed
- Up to 6 pumps dynamically alternated and controlled
