DP400T / TS

DP400T / TS

DP Series is a Multi-stage Dry Vacuum Pump with a pair of lobes and a pair of claw rotors rotating in a synchronous way within the pump casing to form suction and discharge operation.
Oil-free, non-contacting, four stage roots and claw profile make it more suitable for pumping air vapour mixtures. It provides a consistent vacuum with high efficiencies, lowest cost of ownership with adequate safety and performance standards.
The Ts version is a Compact Multi-stage Dry Vacuum Pumping System
A fully automated and self-sustained vacuum pumping system designed with all essential safety features makes it industry ready and a plug-and-play standalone unit.

Pump Technology and Features

Four Stage compression (DP400)

Faster air removal and higher rate of compression

Compact design

Pump mounted on a stand-alone frame occupying a footprint <1sq.m

Vertical mount

Self-draining technology and a vertical mount design make the pump more versatile and rugged

Cartridge-type inlet side bearing

Grease lubricated roller bearing ideal for supporting radial loads. Easy replacement of inlet side roller bearing and seals without removing stages

Angular contact bearing

Double row angular contact bearings near the motor take care of simultaneously acting radial and axial loads

Relief valve

A third stage relief valve avoids high pressure build up within stage compression cycle, if the pump crosses 300mbar

Vision

HHV pumps aims to be a global leader in vacuum pumping solutions, by ensuring the lowest cost of ownership for all our customers.

Mission

Values

  • Maintain safe and clean environment
  • Listen to customers (Internal & External)
  • Repudiate discrimination
  • Integrity and courage to uphold self-belief
  • Excellence through innovation

DP400TS Features

Intelligent In-direct cooling (Thermosiphon)

Unidirectional flow of water through the heat exchanger will eliminate blockages that may occur in industrial water supplies. Cleaning the heat exchanger is also easier if clogging occurs, when compared to the clogging faced within the pump jacket.

Temperature Control System

Helps is preventing condensation/deposition of chemicals in the stages. It maintains the set temperature by controlling the flow of the cooling water through the heat exchanger. The set temperature is defined by the application.

Inlet purge

Protection from process substances entering into the pump chamber and pipe lines through purging a high pressure nitrogen at the inlet.

Shaft seal purge

It is essential to maintain shaft seals at a positive pressure during operation helping to prevent entry of corrosive/toxic gases towards the pump gear cover.
Life of shaft seals increases as we eliminate the risk of damage that may cause from debris or any other corrosive/toxic gases. A controlled and customizable feature helps the user to determine the purge frequency based on the usage and application.

Solvent purge

Internal surfaces of the pump are more prone to corrosion and by-product settlement. This is prevented by running the solvent used for distillation. The solvent purge will rinse the pump internals and keep it safe from possible corrosion and process substances.
