The HMD Kontro GT Pump with an Impressive Range A Small Sealless Pump That’s Big on Value!

AThe HMD Kontro GT Pump has been speci�cally designed as a compact, cost-effective, minimum-maintenance pump for general-transfer applications. The GT is sized to accommodate ASME / ISO dimensions. It displays a number of features that make it one of the most competitive pumps in its class.

Available as free-standing or base-plate mounted, the GT Pump is the result of close-coupled construction. Prime-mover speci�cations of all denominations can be catered to. In addition, the pump is offered in three different sizes, the GT-15, GT-18, and GT-19, along with a range of Synchronous Magnet Drives.

Key Benefits of the GT Pump • Sealless design for total product containment • Low capital cost • Compact modular design • Cost-effective running costs • Minimal downtime • Can be supplied with ASME or ISO Flanges • Maximum interchangeability between spare parts throughout the entire range • Cartridge Assemblies available, allowing fast replacement of the rotating element

Technical Considerations The standard GT Pump is designed to operate in temperatures from -40°F to +500°F without the need for any ancillary cooling. Its standard working pressure is 275 PSI/18.9 Bar. The pump has maximum of 5% w/w less than 150 microns solids handling capability and max 200 CST viscosity handling capability.

SpecificationsLiquid Handling Equipment stocks the GT-15: 1 X 1 X 5, GT-18: 1 X 1 X 6, and GT-19: 2 X 1.5 X 5 ASME sizes with standard construction of 316 Stainless Steel with CSF Casing Gasket, Viton O-Rings, 150# and 300# ANSI RF Flanges, 300°-500°F Temperature Ratings, and standard 275 PSI pressure rating. PTFE Gasket / PFR O-Ring materials are also available, as well as SIC or Graphalloy Bushings. GT Pumps in Alloy 20 Construction are available through the HMD Kontro factory. Cartridge Assemblies and Service Kits for all three GT sizes are on the shelf here at Liquid Handling Equipment.

The previous Liquid Line issue explored the monetary aspect of a motor operating a pump and its effect on the life-long cost of running the pump. What are the steps to ensure that the motor in operation for a particular application is not costing too much money?

The best way to assess if the motor in service is the most cost ef�cient is to determine motor loading. The most common percentages of rated loads are 50% - 100% for electrical motors with the maximum efficiency near 75% of rated load. This means that a 10 HP motor has an acceptable load range from 5 HP to 10 HP with the maxi-mum ef�ciency of 7.5 HP. Do not mistake, however, that the motor should always be loaded at 5 HP or 10 HP for extended periods of time, because it will result in under-loading or over-loading the motor. When under-loaded, the ef�ciency of the motor drops drastically. When over-loaded, it can overheat and lose ef�ciency.

How to ascertain if a motor is properly loaded in order to know when to replace it? The following three input power equations will determine the power at which the motor is operating.

Find the (Root Mean Square) RMS voltage and RMS current from the three different phases, followed by discovering the power factor and expressing it as a decimal not a percentage. To �nd the power factor, Equation 4 below is required. With all of the needed variables, �nd the three-phase power in kW. This power from the motor leads to determining the input power at full-rated load, in order to arrive at a percentage from the two.

Equation 4: Power Factor

Power Factor = kW ÷ kVAkW = kilowattskVA = kilovolts-amps

To find the input power at full-rated load, use Equation 2. Variables are found from the supplier of the motor. With the variables and the found input power factored into the equation, the percentage of the actual output power to the said input power of the motor is available. To do this, divide the output power by the input power to determine the motor’s percent ef�ciency.

The motor’s percent ef�ciency provides the ability to con�rm the motor is properly sized for the application. Motor loads should be tested if they are running more than 1000 hours per year to make sure they are operat-ing at peak ef�ciency.

Equation 1:

Where:Pi = Three-phase in kWV = RMS voltage, mean line-to line of 3 phases I = RMS current, mean of 3 phasesPF = Power factor as a decimal

Equation 2:

Where:Pir = Input power at full-rated load in kWhp = Nameplate rated horsepowerh

� = Efficiency at full-rated load

Equation 3:

Where:Load = Output power as a % of rated powerPi = Measured three-phrase power in kWPir = Input power at full-rated load in kW

Pi = V x I x PF x √3

Load = Pi x.100%

High-viscosity liquids used as components in industrial processes can prove to be tricky to transport and handle. Many such processes require the use of high-viscosity products as ingredients in their �nished products. High-viscosity �uids are also often used to maintain the proper use of machinery.

For example, a specialty chemical-making facility may use concentrated Silica Gels as a key thickening ingredi-ent in its batches. In a manufacturing setting, plants often use large quantities of high-viscosity grease to keep their machinery or �nal products well lubricated and functioning properly. Other industrial settings, for instance a food processing facility, may use thick ingredients such as honey or peanut butter as important �avors in recipes. These are a few examples in which a FLUX High-Viscosity Drum Pump would make transferring high-viscosity liquids an easy task.

FLUX eccentric Worm-drive pumps are suitable for pumping thin-to-high-viscosity fluids. These positive FLUX displacement pumps provide smooth �ow at constant pressures and gently handle shear-sensitive products.

F550 Worm pumps are used in the industrial markets and F560 Worm pumps are configured for the pharma-ceutical, food, and cosmetics industries. All FLUX pumps, which can be used in portable and stationary applications, are comprised of only a few components, making them easy to clean and maintain.

FLUX pumps are available in versions that are immersed in the liquid (top entry), along with a version that can be installed outside the vessel. Pump models are available with 3A certification and single-point grounding for explosion-proof environments. FLUX Food pumps (Directive (EC) 1935/2004 and FDA CFR 21 compliant) are suitable for use in the sanitary and hygienic markets. GS Gear Drive pumps accept FLUX 4 Series motors and the S-�ange pump can be used with industrial motors for higher-viscosity handling. Pair pumps for pumping liquids that are not capable of flowing with the superior FLUX drum-emptying systems for the best success.

A Liquid Handling Equipment Success Story by Craig Sigler

A recent visit to an Ink Manufacturer proved to be well timed.

The plant immediately asked for help with an annoying issue

with its production runs. Its ink production runs constantly

required stopping multiple times to change out cartridge

�lters due to plugging. The manufacturer’s �ltering process

was to use a 1 micron �lter that �owed into a 0.5 micron

�lter, ending each run with a 0.2 micron �lter. The problem lay with the 1 micron

and 0.5 micron filters, requiring replacement at least three times during every

production run.

StrainRite, a top-notch filter manufacturer Liquid Handling

Equipment represents as a Master Distributor, was

introduced to the ink manufacturer. Meeting with the

customer to learn about product make up and �ltering

procedures for a variety of inks, Liquid Handling, along

with the help of StrainRite, provided the ideal solution via

the Madd-Maxx Cartridge Filter product line. This filter

consists of 41 square feet of filter media in a Size 2 filter.

The larger area of the �lter optimizes element �ow rate.

StainRite filters and housings were provided to the plant on a trial basis for

its most prodigious production run. The recommended �lters successfully

completed the production run without any downtime. The run was more

time ef�cient than previous stop-and-start production runs. Even more

impressive, a lab quality check found the ink product to be above the

required benchmark set by the customer.

Needless to say, the manufacturer is extremely pleased, thanks to the superior

StainRite filters. Liquid Handling Equipment’s association with StainRite

ensures satisfactory solutions to challenging �lter problems.

Contact your Liquid Handling Equipment representative

to learn more about the StainRite product line

to eliminate demanding filter problems.
