Walchem announces the Digital EZB Series of Metering Pumps. These pumps are designed to operate in most metering applications with a wide variety of chemicals. The digital control enables quick adjustments and easy operation. The clear resolution of the LCD aids programming. Combining low cost, a 360:1 turndown ratio and high-speed operation, the pump is the practical solution to cost-sensitive applications requiring high turndown capabilities. They’re solenoid-driven diaphragm metering pumps with output capacities up to 3.2 gph (12.1 L/h) and pressure capabilities to 150 psi (10 bar). By pumping at 360 strokes-per-minute, they minimize chemical slug feeding commonly found in slower pumps. With a fixed stroke length and sealed digital control panel, they provide an IP65 solution fit for harsh environments. When tight or limited-access applications are an issue, the digital control module can be mounted remotely from the pump end.

Flowserve Corp. adds two new sizes to the Flowserve Limitorque PT series of worm gear operators. The PT series is built to provide the torque needed for operation of quarter-turn valves used in water and wastewater treatment, petroleum refining and distribution, and other industries. The new PT-12 and PT-14 models, rated at 880 ft-lb and 1,600 ft-lb respectively, are designed to provide added versatility for torque and operating time requirements. Like the larger worm gear operators in the PT product line, they’re made with a rugged cast-iron housing for weatherproof, submersible or buried service applications. While the PT can be used for manual valve operation, motorized valve control using the PT offers superior process control.

The Moyno® 300 Series non-motorized pump is a cost-effective, compact sized unit that offers significant application versatility. These general utility, progressing cavity pumps, also available in motorized versions, provide dependable performance and long life in handling a wide variety of fluids from glue to jet fuel and swimming pool drainage. They handle clear liquids as well as viscous, corrosive fluids. The non-motorized model allows the end user to choose the means by which the pump is powered, whether with a gear motor or a belt drive configuration. Featuring a fully-molded “wobble” stator, this design increases compression fit during operation between rotor and stator, resulting in improved pumping performance. All 300 Series pumps are self-priming with a non-pulsating, low-shear flow which remains steady even under wide variations in suction head.

The 130 Series reversing control from Dart Controls uses the company’s zero-speed detect and solid state dynamic braking circuits. These circuits eliminate the contact arcing and failed braking problems associated with other reversing and dynamic braking controls. Its zero-speed detect circuit also eliminates motor plug reversing problems. In the event of a power loss or emergency stop condition, the 130 Series control will drop into a dynamic brake condition to safely bring the motor to a stop and remain there until power is reapplied and a run condition is recognized.

OCV Control Valves manufactures a variety of pump control valves and designed its Series 125 specifically to eliminate surges associated with starting and stopping a pump. Smooth discharge and volume are produced by electrically interfacing the valve with a pump motor that opens and closes the system at an adjustable speed. The valve has a built-in flow check feature to prevent back flow and automatically shuts the pump motor off on loss of pump discharge pressure. The rectangular-shaped, soft seat seal provides drip-tight Class VI closure while the throttling seat retainer generates flow and pressure stability. The 125 is equipped with a replaceable seat ring, alignment pins for proper reassembly after maintenance and can be serviced without removal from the line.
