Fluid Power

VERTICAL PUMP

Good for confined spaces

The Moyno(R) vertical pump can be mounted to closed tanks or to mounting beams above open tanks. The pump pulls fluid from the bottom of its storage container and discharges it at the surface for further processing. This pump is good in situations in which there is limited space. Its compact, vertical, close-coupled design can fit into many tight spaces. Some additional features are the flow range of 20-35 gpm, pressure capabilities of 150 psi, ability to handle high viscosity and high solids content material, and low shear fluid transfer.

FLOWMETER

Microprocessor-controlled

These Smart flowmeters are designed specifically for all gas and steam applications. The devices compensate for the material's pressure, temperature, and viscosity that they are handling by being microprocessor-controlled. Other features include a flow range as low as 0.4 scfm, wafer and insertion styles, built-in temperature sensors, 70 to 1 dynamic range, drift-free performance, minimal pressure drop, and no moving parts, making the flowmeters maintenance-free. The flowmeters are also calibrated to NIST traceable standards. J-TEC Associates Inc. http://rbi.ims.ca/3854-607

BAG FILTER

No need for overhead lifting devices

Featuring a 24 filter bag model that handles flow rates of up to 4,500 gpm, the MAXLINE(TM) MBF HD multi-bag filter housing is a bag filter that is available in either carbon steel or stainless steel. The MAXLINE MBF HD has incorporated a hand wheel-operated davit cover into its design to combat the problem of replacing filter bags, which was a problem prior to this because of the heavy cover present on many model's bag filters. Designed to accept the many different size 02 filter bags available from Hayward, the filter will also work with standard 7-x 32-inch bags. Hayward Industrial Products Inc.http://rbi.ims.ca/3854-608

PIEZOELECTRIC PUMP

Miniature in size

The DTI-200-12P and DTI-200-12A models of miniature piezoelectric pumps feature technology that solves size problems, power consumption, noise, and reliability for a range of liquid and gas pumping applications. The pumps operate when the bonded piezoelectric crystals are stressed and distorted by an electric field, which causes the diaphragm to flex and two check valves respond to this flexing to create a pumping action. Electromagnetic noise is eliminated because there are no electric motors. Both pumps have a pump life of 10,000 hrs and can deliver flow rates of up to 200 ml/min for water and 7.5 SCFH for air. Clark Solutionshttp://rbi.ims.ca/3854-621
