Multistage Horizontal Pump – HPS
Nova’s Multistage Horizontal Pump is a cost effective, low maintenance solution for high volume, high pressure fluid movement.
COMPONENTS:
Pumps, Thrust chamber, Intake, Discharge, control, instruments, Skid, and Motors.
PUMP
Standard material of construction for the impeller and diffuser is ASTM A436,
Ni Resist Type 1 with high nickel iron, which gives excellent corrosion and erosion resistance properties.
For severe environments, optional Tungsten Carbide, radially Stabilized, and corrosion resistant pump materials, or hardening of components are available.
Due to the limited diameters, the lift or head developed by an individual stage is relatively low. This requires stages to be stacked together to meet the lift requirements for various applications. At each stage the rotating impeller adds velocity to the fluid stream by centrifugal force and tangential redirection at the impellers outside diameter. The stationary diffuser converts this high velocity energy to pressure as it redirects the flow to the next impeller. Diffusers also act as a bearing surface, providing additional stability to the pump shaft. (Master Chart)
Standard Shaft Materials is high strength K-500 Monel and it will be available on
17-4PH, Nitronic 50 or Inconel material.

THRUST CHAMBER
Nova’s Unique Thrust chamber offering Improved most reliable in the industry, the pumps used for surface pumping on compression stage design with this arrangement all of the impellers are fixed to the pump shaft and act as a single body.
The thrust chamber rating is for 25,000 Lbs, with Intake Pressure of 2100 PSI, with availability of the intake Flange up to 12 Inches. Standard intake pressure is 150 PSI.
This design allows all of the thrust that is developed in the pump to be carried by an external bearing chamber, which during normal operation there should be no axial contact between the impellers and diffusers in the pump.

DISCHARGE-INTAKE
Discharge is a flange bolted to the pump head and sealed with O-rings.
Standard Discharge in ISO or ANSI flange are available in different custom sizes, 4″, 6 Inches up to 12 Inches up to 5000 PSI.

SKID
Steel I-Beam Base Plate, with pump supports, painted are as package of the Multistage Horizontal Pump. Each MHP is delivered to location with all components mounted and ready to Operate. No field alignment is necessary all components can easily be serviced on location.
Motor
The motors are three phase induction motor, typically two pole 3600 rpm, for low head applications 4 pole motors can be used. Motors are directly coupled to the thrust chamber.
The motor most often selected is a TEFC. Gas or diesel Drives are available. With a gas engine a 2:1 speed is required and accomplished with a Gear Box.

INSTRUMENTATIONS :
Switches and/or sight glasses provide monitoring functions for the unit. High Vibration Switch Ex-proof, Low Oil Level in Thrust Chamber Switch Ex-proof, Thrust Chamber Oil Temperature Switch/Gauge Ex-proof, Low Suction Pressure Switch/Gauge Ex-proof, High Discharge Pressure Switch/Gauge Ex-proof, Thrust Chamber Pressure Switch/Gauge Ex-proof.
- Low Suction pressure, is used to shut down the system is suction pressure is lost.
- Discharge high pressure, is used to prevent over pressure or a dead head condition.
- Low flow can be used to prevent operation with out fluid or dead head.
- Low oil level protects against thrust chamber oil loss.
- Vibration is not intended as a diagnostic tool but to shut down if a major problem occurs.
- Lubrication pressure, for high load applications with pressure lubricated thrust bearings, prevents loss of oil.
- RTD’s shuts down the motor if winding or bearing temp rises to high
- Tank level, used to control flow with a flow control valve or a VFD to maintain a tank level.
- Variable speed controller, A motor controller that varies the frequency of the motor to change the operating speed.
IMPROVING RUN TIME
Internal Polymer coating and tungsten carbide bearings are available on request to improve reliability of the pumps to prevent premature failure due to commonly problems like corrosion.
