Basket Type Line Strainers - Viking Bolted-Lid Simplex Strainers

Viking Bolted-Lid Simplex Strainers provide protection for your pumping system with low pressure drop. The inclined position of the strainer basket adjacent to the porting provides smooth flow patterns not found in conventional basket-type strainers.

These Basket Type Bolted-Lid Simplex Strainers reduce cleaning problems encountered with conventional strainers. The basket is removed from the top of the strainer, possibly eliminating the need to completely drain the system or allowing foreign matter to drop back into the line when the strainer is cleaned. The relatively small port-to-port dimensions of the strainer allow easy installation. Strainers are designed with a tapped port in the lid to easily attach an air eliminator. Strainers are also equipped with a bottom drain plug for complete draining of strainer if needed. They are also equipped with pressure indicator ports.

Lid-Ease® Strainers
Designed for convenience and efficiency, the quarter-turn breech-lock lid offers quick access for routine cleaning. The inclined basket minimizes pressure drop, maximizing system performance, while the top-access basket removal eliminates strainer drainage—reducing product loss and streamlining maintenance.

4924A Series Liquid-Specific Refrigeration Ammonia Internal Gear Pumps

Viking’s 4924A Series™ Positive Displacement (PD) pumps offer safety, reliability and high efficiency in refrigeration ammonia recirculation applications. Safety is achieved through use of a double mechanical dynamic shaft seal located between bearings for minimum possible shaft run-out, with a pressurized barrier fluid system, and O-ring type static seals where components are joined.

Reliability is provided by slow speed operation and low differential pressures, which maximize bearing and seal life. And efficiency is inherent in the PD Internal Gear pumping principle, compared to centrifugal pumps. Viking pumps can usually use at least one motor size smaller than these technologies.

AMMONIA (REFRIGERANT R-717) - Ammonia (Refrigerant R-717) is a very thin liquid that is a gas at ambient temperature and pressure. It is typically kept at elevated pressure to keep it in liquid form. Ammonia is used as the refrigerant in cooling systems.

In vapor compression ammonia refrigeration systems, liquid ammonia in the evaporator coils absorbs heat, and some flashes to a gas before recompression. Viking pumps “overfeed” the evaporator to ensure that the ammonia in the evaporator coils is liquid, which is more efficient at removing heat than a gas. Viking 4924A Series™ draw liquid ammonia from an accumulator vessel and pump it to the evaporator and back in a closed loop. Liquid and gaseous ammonia are separated in the accumulator and the gas is recompressed and flows to the condenser where it rejects heat, then to a receiver and back to the accumulator in a closed loop. The Viking pumps’ slow speeds enable very low NPSHr to prevent flashing and cavitation. Their high efficiency, with air-cooled motor, add almost no heat to the system, increasing overall cooling efficiency.

Viking Pump 4924A Series Features & Benefits
• Pressurized oil reservoir ensures barrier between inboard and outboard seals.
• Sight glass enables easy verification of oil level.
• Rotatable bearing housing simplified end clearance adjustment.
• Return-to-tank pressure relief valve prevents overpressure (HL valve shown. Others extend with poppet parallel to shaft).
• Rigid, one-piece cast iron bracket with seal between bearings helps prevent misalignment to ensure long seal life.
• Double mechanical seal with oil barrier for maximum safety.
• Lubricated idler bushing with pressure lubrication system (K, KK, LQ, LL sizes) provides constant film of liquid between idler pin and bushing for long life, regardless of pump rotation.
• Static o-ring seals between casing, head and bracket provide superior joint sealing.

75 Series Motor Speed Product Line Cast Iron Internal Gear Pumps

For compactness, less weight and simplicity of mounting, Viking’s 475 line of close-coupled pumps are ideal for direct connecting to other pieces of equipment.

The positive, smooth delivery of these pumps makes them preferred for many types of applications including filtering, circulating, transferring, lubricating or booster service. The five sizes of Viking close-coupled pumps from 5 to 30 GPM are available in this unmounted type ready to connect on other equipment with standard NEMA C flange mounting.

All 75 series model pumps are available with rotor bore to fit the shaft of a standard motor or other piece of equipment. Bores are furnished in ⅝” and ⅞”. By using a full length key between drive shaft and rotor bore, rigid and positive alignment of pump and drive shaft is assured. This advanced design is unique in its field for it permits use of STANDARD, unmodified NEMA C flange ball bearing motors. It is extremely close-coupled, reducing needed space, cutting overall weight, eliminating bases, couplings, outboard bearings or any drive equipment and at the same time saves cost. All sizes are equipped with opposite ports. Only two casing sizes are used for all five pumps. The two smaller pumps use one casing and the three larger pumps use the other.

These gear pumps are built to accept a compact, integral relief valve mounted on top of casing to maintain extreme compactness. All pumps are available with either mechanical seal suitable for 100 PSI pressure or a lip seal suitable for 50 PSI. No modification of parts are needed to convert from one seal to the other.

Viking SG is an extensive series of precision, industrial-duty external gear pumps that develop higher pressures than other Viking pumps, yet offer a similarly broad range of options to handle a diverse range of liquids and applications. With 26 different displacements in five frame sizes to 190 GPM (719 LPM), most applications can be closely matched to a pump operating at motor speeds, without the need for a reducer or gear motor.

The SG-X Series™ UL listed motor speed pump is for fuel oil, providing the best solution for this liquid. It can handle flows up to 11 GPM (42 LPM).

These pumps were designed for greatest reliability, with standard features like spur-type gears (instead of helical gears, which thrust into pump casing and bracket) and rolling element anti-friction bearings (instead of bushings, which wear every time a pump is stopped and the hydrodynamic
film is lost).

Unwanted leaks are prevented by using the best sealing technology available, including single or duplex lip seals, single mechanical component seals, and single or double mechanical cartridge seals with seal plans (SG-10 Series™ & SG-14 Series™ only). Installation is simple, with brackets to close couple to NEMA or IEC motors, or foot mount for speed-reduced applications. Piping is easy, with straight-through, 180° ports with the industry’s broadest variety of threaded ports and flange options.

SG-805 | SG-807 Series Motor Speed Product Line Ductile Iron External Gear Pumps

Where shaft seal leakage is not allowable, for liquids that are hard to seal, or where seal maintenance is difficult, Viking Mag Drive® sealless external gear pumps are the solution.

In this type of pump, a canister hermetically seals the liquid within the pump. Inner magnets are connected to the pump drive shaft inside the canister, and an outer magnet assembly rotates outside of the canister, driven by a motor or other drive, so that magnetic forces pass through the canister to the inner magnets and cause the drive shaft to rotate. This eliminates traditional dynamic shaft seals, and problems associated with them (wear, leakage, air infiltration).

A hollow drive shaft allows some liquid to flow by means of pressure differential from the high pressure side of the pump through the shaft, into the canister and back to the low pressure side of the pump. This provides magnet cooling and prevents product stagnation.
