Chopper pumps

The ChopX Series pumps from Hayward Gordon are designed to simultaneously chop and pump the most difficult solids, eliminating the need for grinders and comminutors. The pump’s impeller features cutting edges on both the front and back to allow for the reduction of solids passing though the pump, while eliminating clogs due to solids build up. A disintegrator blade can be added at the inlet to further assist in the break-up of solids. Two blade and four blade impellers are available depending on the application requirements, making the pump ideal for scum pit, digester recirculation or digester scum blanket applications. For abrasion and corrosion resistance, the pump is available in a range of materials, including Ni-Hard, High Chrome Iron, hardened alloy steels, stainless steel and other corrosion resistant metals.

Backflow protection

Tideflex Technologies’ Waterflex® Check Valve features a wafer design that provides low headloss in high pressure potable water applications. It operates solely on line pressure and backpressure, no outside energy source is required. Forward hydraulic pressure folds the elastomer disk away from the perforated plate to allow flow. Reverse pressure seals the disk against the perforated plate to prevent backflow.

The new DM 15 Digital Display from Fluid Components International (FCI) serves as a remote digital display that indicates flow rate or temperature readings using FCI’s ST and GF Series thermal-dispersion mass flow meters. Offering user flexible in terms of input and display, the unit is a DC input indicator that also offers a hi/low alarm set-point option that can be set to any point plus-or-minus within its measurement range. The display is an AC-line powered meter with a bright red LED readout. It features a push-button scalable +9999 digit display and will accept either 4-20 mA or 0-10 vDC output signals from FCI flow meters. It is ideal for a wide range of air, gas and fluid process control applications where accurate flow measurement is essential to the integrity of the process.

Water level indicators

Upgrading its line of water level indicators, Durham Geo Slope Indicator (DGSI) has announced the immediate availability of laser-marked cable shipping with new units and as a replacement for standard cables on previous water level indicators. The water level indicators employ graduated cables rather than tapes. Cables are easier to reel in and out and they don’t kink like tapes. The steel conductors inside the cables also provide excellent dimensional stability. Now, the cables are laser-marked resulting in clear, high contrast inscriptions that are a permanent part of the cable jacket.

Blue-White has introduced the New Micro-Flo Digital Flowmeter. The new meter is ideal for measuring flow on most metering pumps. Programmable units of measure are: gallons (U.S.); liters; ounces; and millimeters. Programmable time units are measured in: minutes, hours, or days. The six digit LCD display has up to four decimal positions. Both rate of flow and total accumulated flow are displayed. The flowmeter features non-volatile programming and accumulated flow memory. The total reset function can be disabled to prevent tampering. Additional features include a clear PVC viewing lens or PVDF chemical resistant lens; weather resistant Valox PBT enclosure, and a NEMA 4x rating. Three model variations are offered: FS = Sensor mounted display; FP = Panel mounted display (includes 25' cable); FV = No display, sensor only, 5 vDC current sinking output (includes 25' cable).
