Features

The V Series Asphalt Pump 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 Internal Gear Asphalt 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 asphalt pump. Replacing an existing Viking gear 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 asphalt 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 V Series Asphalt Pump 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
