Viking Pump 4223C Series Features & Benefits
• Positive displacement internal gear pump principle handles a broad range of viscosities with constant flow rate.
• Jacketing for steam, hot oil or warm water circulation.
• ProPort™ Casing (4223C Series™): » Adaptable port design offers a variety of port sizes and types, enabling flexibility when connecting pumps to piping. » H-Q sizes available with optional opposite porting. » Casing drain allows the pump to be drained without removing the head. » Optional O-ring joint seals for high pressure or difficult to seal applications. » Internal circulation promotes flow behind the rotor.
• U-Plus™ Bracket (4223C Series™): » Seal options include packing, single component seals,cartridge lip seals and both single and double cartridge mechanical seals. » Stainless steel window guards offer protection from rotating parts.
• Footed one-piece steel bracket provides rigid mounting to help maintain alignment, which extends seal and bearing life.
• Enlarged bearing housing used in conjunction with a spacer coupling permits easy cartridge seal installation and removal in place without removing the head and rotor/shaft.
• Axial rotor thrust is controlled by double row ball bearing or tapered roller bearings; bushings provide a secondary point of radial shaft support.
• Rotatable bearing housing provides easy rotor end clearance adjustment to compensate for viscosity or wear.
• Numerous material options are available for bushings, idler pins, shafts, rotors, idlers and elastomers.
• Carbon steel externals offer higher temperature and maximum working pressures
