The new GNX and GNXH Series Sliding Vane Pumps are designed to handle a wide range of non-corrosive, non-abrasive industrial liquids and petroleum products. Manufactured with a large operating range, these pumps offer high flows and high pressure. They are currently available in 2- and 2.5-inch flanged port sizes. Larger 3- and 4-inch flanged port sizes will be released later this year. Combined, these sizes provide flow capacities ranging from 20 to 500 gpm (76 to 1,893 l/min) at working pressures up to 175 psi (12.1 bar).

The Wilden Advanced FIT pumps feature bolted product containment and easier maintenance. No repiping necessary, the Advanced FIT pumps precisely fit bolt-to-bolt and pipe-to-pipe in existing fluid-handling piping systems. The FIT pumps come equipped with the wetted path that minimizes the number of fasteners and allows for single socket reassembly for faster, easier maintenance. These pumps also come equipped with the energy-efficient Pro-Flo Shift air distribution system.
IntelliflEx is the name of a completely new approach towards design and technology for progressing cavity pumps. This highly efficient pump, based on the valve-less positive-displacement pump technology combined with intelligence of computer and software.
All components are reflecting the fundamental ideas which lead to the innovation: Make progressing cavity pumps greener:
- Stainless steel for the housing of motor and drive,
- natural granite stone instead of cast iron are not only eye catching design details.
The “D” in AHD stands for Duplex, which means the reinforcement of the drive pressure is more than 2:1 by the internal pressure boosting stage. This is achieved thanks to a maximum drive pressure of 7 bar (100 psig), which allows the AHD to build up discharge pressures up to 15 bar (218 psig). AHD Series pumps are available in three sizes (AHD 15, 25 and 40) with maximum capacities of 4, 10 and 20 m3/h (17, 44 and 87 gpm).
The new AHS Series, which does not include an internal pressure booster, features an extremely rugged housing making it suitable for higher discharge pressures. The “S” in AHS stands from Simplex, meaning the drive pressure is transferred to the medium in a ration of 1:1.
The G Series models 3”, 4” and 6” metal sealed internal gear pumps are available in cast iron, carbon steel and stainless steel materials. Delivering flow rates up to 500 gpm, these pumps are offered with both packing and mechanical seal options and can be used for a wide range of application types. The EnviroGear G Series sealed internal gear pumps are durable and an excellent cost-effective choice for your challenging liquid transfer needs.
The actually supplied two canned motor pumps, with “tandem” design, convey the medium [C3 fraction with propylene as main constituent] at a temperature of 22 °C. The differential head [H] is 379 m at a flow rate [Q] of 7.8 m³/h. The pump units are designed for a nominal pressure of 40 bar and have temperature- and level-monitoring features. For online monitoring of the hydraulic axial bearing, a rotor-position monitoring feature is also provided.
The special tandem design of the multistage pumps results in minimal shaft deflection and load relief at the slide bearings. The “ZART” (Zero Axial and Radial Thrust) technology ensures a contact- and wear-free running of the rotor unit.
The 420/430 Advanced FIT pumps have been specifically designed to be direct replacements for existing 38 mm (1-1/2”) pump installations. The release of the aluminum 420/430 Advanced FIT pumps now completes the Advanced FIT pump line, which is available in 38 mm (1-1/2”) through 76 mm (3”) sizes with either aluminum or stainless steel wetted path options.
The Sundyne LMV-803Lr is an API 610 compliant pump available in either OH3 or OH5 motor mounting configuration that provides ultra-low NPSHr performance – approximately 5 ft (1.5 m), across the entire performance range – for flows to 800 GPM (180 m³ / hr) and heads to 1,000 ft (305 m).
The ultra-low NPSHr allows the pump to be installed at grade level, eliminating the expense of installation in a pit and performing maintenance in a confined space. The vertical design is ideal for use in refineries, NGL, petrochemical and chemical plants, as well as handling light hydrocarbon handling services, such as bottom pumps for de-ethanizers.
S Series are self-priming double-ended positive displacement pumps available with or without external timing gears and bearings. Twin and triple screw designs provide complete axial balancing of the rotating screws and their timing technologies eliminate metal-to-metal contact with the pump.
S Series pumps are Atex-certified for use in explosive or dangerous environments, and have been specifically designed to address the difficult pumping challenges found in the oil & gas, process and marine industries. S Series pumps provide solutions that can meet the toughest application challenges regardless of temperature, viscosity or pressure.
The NPH and XH series complete the NP and X series of these pump families. The new feature of both series allows the user to choose between 90- and 180-degree porting.
The XH pumps are designed to handle a wide range of non-corrosive and non-abrasive industrial liquids and petroleum products The NPH pumps are built for handling viscous or shear-sensitive fluids. Both models are available in 2”, 2.5”, 3” and 4” (51 mm, 64 mm, 76 mm and 102 mm) sizes.
