4624B Series Liquid Specific Viking Pump
The Abrasive Liquid Series heavy duty internal gear pumps utilize hard parts in key wear areas, combined with unique designs and operating practices to reduce abrasive wear for longest life. These pumps are ideally suited for liquids with concentrations of small but hard particles, such as paints, inks and pigments; filled polyols and resins; and waste oils.
The 4624B series pumps replaces the old style 4625 series, offering the advantage of a one-piece bearing housing for faster and easier end clearance adjustment and adding the LS and QS sizes. The F & FH4624B pumps are identical to the old F & FH4625 pumps. Jacketing is available by ordering a 4224B model with abrasive fitting (tungsten carbide idler pin and bushing, abrasive liquid seal with flush line). All models are dimensionally interchangeable with the old 4625 series, except:
• The L, LQ & LL4624B sizes have a more robust1.44” diameter shaft, while the old 4625 models used a 1.13” diameter shaft
.• The M4625 has been discontinued.
• The QS4624B provides equivalent performance, but is not dimensionally interchangeable
