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.

Available Materials
  • Cast Iron
Max Temperature
  • 450°F (232°C)
  • 90 gpm to 450 gpm (20 m³/h to 102 m³/h)
Max Pressure
  • 100 psi (6.9 bar)

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

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.


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.


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.
