EnviroGear® V Series Pumps Kicking Viking® in the Asphalt

Introducing the EnviroGear® V Series Asphalt Pump. We understand that pumping asphalt is a challenge as it changes temperatures and can range from a solid to a liquid with a wide variety of fluid characteristics depending on the chemical makeup. And - let’s face it - the competition isn’t getting the job done. EnviroGear V Series pumps address and overcome these challenges, and do so in a way that is safe, reliable and economical.

Features

The V Series’ innovative design includes a wide variety of new and standard-setting features that have established a series of industry firsts within the asphalt market.

Industry’s Largest Jacketed Surface Area

The V Series Pumps feature up to 35% more jacket surface area than the competition, which improves system reliability by incorporating the following features:

  • The unique ability to utilize the jacketed head and pressure relief valve (PRV) simultaneously
  • Jacketing located behind the pump rotor, which removes a known cold spot that can result in hard startups and premature pump and seal failures
  • The industry’s largest jacketed surface area on the pump case and PRV that enables uniform heating whether using steam or hot oil

v-series_direct-replacement

First Direct Replacement for Viking® 34 Series Pump & Parts

First drop-in replacement for the Viking® 34 Series Pump. Replacing an existing Viking pump usually requires no modification to the piping, driver, baseplate or coupling, while also keeping flow rates unchanged. V Series components are also part-for-part interchangeable with the Viking 34 Series Pump and offer very specific design enhancements to improve reliability. See our Cross Reference Guide.

ve-series_rotatable-flanges

Rotatable Flanges

Allows the operator to use both right-handed and left-handed flange orientations as needed without additional lead times or costs associated with left-hand configuration pumps.

v-series_ductile-iron

High-Strength Ductile Iron Gear Material as Standard

High-strength ductile iron is EnviroGear’s standard offering with other hardened material component options available to provide improved pump life:

  • Surface hardened case, head, rotor, idler and shaft
  • Special high-temperature hardened steel idler pin
  • Hardened cast iron idler bushing, RBS radial bushing, and stationary thrust washer

1Rotor Bearing Sleeve (RBS)

The Rotor Bearing Sleeve (RBS) and seal chamber is designed to accept a wide range of bushing options as well as sealing technologies such as packing, cartridge triple-lip seal, and cartridge mechanical seal.

2Rear Plate with Jacketing

Provides jacketing behind the rotor to eliminate cold spots

3Heavy-Internal Clearance Options

A wide range of internal clearance options are available, which allows optimal performance in a wide range of applications

4Hardened Idler Pin

Standard on all pump sizes for maximized operational life

5High-Strength Rotor Standard

High-strength, ductile iron rotor comes standard on all sizes, eliminating the need for costly, long lead-time steel rotors

6Jacketed Head with PRV

Jacketed head designed to incorporate an optional pressure relieve valve (PRV), offering pressure protection with improved head heating

7Seal/Packing Gland

Securely houses seal or packing around rotor shaft.
