Product Overview
- VGP – series Vertical Glandless / Sealless Pumps are specially design to remove the problems arising from the use of Mechanical Seals, Stuffing Box Gland and Dry running in all types Centrifugal Process Pumps.
- These pumps have no Mechanical Seal or Gland. These pumps are absolutely Sealless and Glandless
- The Pumps are having similar design to any conventional Centrifugal Pump. It differs in so far as, it is always mounted in the vertical position. A restriction is provided above the impeller and the need for any form of liquid seal is obviated by allowing a small leakage to escape by way of an overflow connection in the upper pump body and return to the suction vessel. The Volute Casing & Impeller are made from UHMWPE and also the Expeller & Over flow Casing Cover is made from UHMW.PE materials to give max. High Mechanical & Abrassion strength to pump. The Pump is supported by CI mounted bracket with SS Bolts & Nuts.
UHMW-PE Pumps Properties
- UHMW-PE (Ultra High Molecular Weight Polyethylene) is an extremely tough and abrasion resistant thermoplastic that is used for applications that require durability and/or abrasive wear resistance.
- It is superior than PP / GFRPP in terms of abrasion resistance, mechanical strength and toughness
- It is not possible to process UHMW-PE through conventional methods such as injection, blow or extrusion moulding, because this material does not flow even at temperatures above its melting point. It demands special processing techniques, being the most common RAM extrusion and compression moulding.
- Key Characteristics of UHMWPE
- Excellent Abrasion Resistance and
- Mechanical Strength
- Good Chemical Resistance.
- Extremely Tough and Durable.
- Low co-effcient of Friction (Selflubricative)
- High Impact Strength.
- No absorption of liquid
Technical Specifications
| Capacity | Up to 200 m3/hr |
| Head | Up to 100 meters |
| Temperature | Max. up to 100°C |
| Maximum Working Pressure | 10 bar |
| Pump Speed | 1440rpm , 2900 rpm |
| Max. Sp. Gravity | 1.2-2.0 |
| Viscosity (upto) | 150 mPas (cP) |
| Suction & Discharge | ANSI B16.5–Class#150 |
Salient Features
- No gland or mechanical seal, Hence problems associated with gland packing or mechanical seal are completely eliminated.
- Zero safe minimum flow
- Pumps can run dry indefinitely due to absence of mechanical seal but only untill the melting point of (i.e.100°C) with no damage to the pump.
- Direct assembly with the motor also available to avoid issue of misalignment and eliminates the problem associated with maintenance of bearing housing (D-type). Note:- coupled assembly are also available for easy maintenance of the equipment by having quick dismantling of motor and pump (L-type).
- Saves valuable floor space due to the vertical installation of the pumps.
- Ideally suited for continuous operation
- Suited for clear clean liquids, slurry application and mainly for the ETP Plants.
- Offered in 1440 and 2900 RPM.
- Suited mainly for slurry application and mainly for the ETP Plants.
- For Scrubber, Ejector etc Mechanical seal type designed is also available so to assure no gasses are coming out and no pressure is loss in pumping system. Seal failures in this type of arrangement is much lesser as very less pressure is observed on the seal during operation and hence seal life increases.
- Pumps complied to ISO 5199 / 2858
Principe of Operation
- The liquid entering through Suction via Impeller Eye of Impeller Flows around the Impeller Casing and leaves through the Discharge under pressure.
- But some liquid escapes to the Overflow Chamber (Casing) through the annular gap between Impeller Casing & Impeller.
- The auxiliary Impeller (Known as Expeller) prevents the leakage liquid going further up and channelizes it through outlet in the Overflow chamber (casing) and hence there is no leakage through pumps avoiding the use of any mechanical seal or stuffing box gland.
Application
- Mainly for handling Highly Corrosive & Abrasive Slurry (20 %)
- Effluent and Water Treatment Plants
- Gypsum Slurry, Lime Slurry based liquid, CACL2 Filter Press application
- Handling Acids and Alkalis
- Phosphoric Acid plants
- Gas Washing Plants & Rayon Plants
- Chemicals, Dyes & Pigments Industries
- Organic/Inorganic Chemical Industries
- Pickling in steel Rolling mills
- For Descaling & Electroplating Plants
- Fertilizer & Agro – Chemical Plants
- Textile, Pulp and paper industries
- Caustic Soda & Chlorine Plants
- For Scrubbers, Filter press, Ejector systems etc
