accessories available with parag make oil seal high vacuum pump

Accessories:

Air Ballast:
This is a vent pipe introducing air before actual compression which eliminates condensation of the sucked vapour, there by avoiding contamination of oil.

Air Admittance Valve:
It is electromagnetic solenoid type which admits air into the system as soon as the power supply fails. This prevents back-flow of oil to the system.

Non-Return Valve:
It is rubber diaphragm type, spring loaded valve, which prevents back-flow of oil to the system as soon as pump stops. These can not be used to hodl the vacuum in the system for longer period.
Moisture Trap, Inlet Dust Filter, Vacuum Gauge with Regulator, Trolly for small Pumps.
USE Oil: ENCLO - 46 (HP) SAE - 30 or Equivalent Vacuum Oil.
Model HL - 300 - II and above, are provided with water cooling jacket.
Vacuum Measured Mcleod gauge at suction port of the pump.

operating principle , liquid ring vacuum pump

Operating Principle:
The working parts of the Parag Pumps cossets of amulti-vane impeller mounted eccentrically in a round casing which is partly filled with liquid (usually water). As the impeller rotate the liquid is thrown by centrifugal force to from a liquid ring which is connector with the periphery of the casing. Due to the eccentric position of the impeller relative to the casing and liquid ring the spaces between the impeller vanes fill with liquid during rotation and any air or gas trapped in the impeller space or cell is compressed and discharged from the casing through the outlet part leaving the cell available to receive air or gas as it is presented to the inlet port of the casing. In addition to being the compressing medium the liquid ring performs three other important functions. It absorbs the heat generated by compression nd friction.

features of parag make water ring vacuum pump

Features:

Entrained liquid drops, Condensable vapours or occasional slugs of liquid can be handled without damage to the pump or significant effect on capacity. In the case of vapours, the pump can also serve as a condenser.
No lubricant or oil is required within the pump itself. Thus the air or other discharge gases are not contaminated. The liquid which forms the ring (usually water) serves both as a sealant and a pumping media.
A wide selection of materials and seal liquids can be used when corrosive gases and vapours are being pumped.
The pumps contain no metal parts that rub against each other. Packing glands and bearings are accessible from the outside. There is no clearance volume and the pumping action is smooth and uniform (non-pulsating).
The only moving part is a balanced impeller which reduces noise and vibration. This means lower foundation, installation and service costs.
The pump can be provided with partial liquid recycle, closed loop liquid operation, automatic control and other features.
Mechanical seals can be provided as an option.
Small entrained solid will pass through the pump. However, abrasive particles will result in reduced pump life.
Each pump is performance tested prior to shipment.

advantage of using fluid coupling aka hydraulic coupling

Inherent Advantages:
  1. No wear of power transmitting elements
  2. Motor always starts unloaded. So, it accelerates quickly to its optimum speed at which it delivers its peak torque.
  3. The torque multiplication at start-up, enables a motor to be selected for running power of a machine, instead of its starting power required. Thus, acceleration of high inertia load is possible by a comparatively low powered motor. The rate of acceleration can also be controlled by varying the oil filling quantity. The shock free, smooth load take up is of great importance in some application.
  4. Maximum torque capacity of a coupling can be adjusted and limited to predetermined value to suit the motor or the machine, by adjusting the oil filling quantities.
  5. Simple, robust and more reliable, squirrel cage motor with simple star-delta starters combined with fluid couplings, can be employed for applications - which otherwise, require costly, special motors with even more complicated starting gears.
  6. The coupling, effectively dampens the shocks and torque fluctuations. Also protects motor from sudden jamming of machines. A fusible plug allows the oil to escape out and isolates the motor in case of prolonged delay in clearing the obstruction.
  7. Automatic load sharing and synchronization is achieved in case of multi-motor drives.
  8. Braking of a running machine can be effected by reversing the rotation of motor. The opposite torque developed by the reverse rotation of motor stops the machine.
