Product descriptionThe MTA pumps are designed for pumping of coolinglubricants for machine tools, condensate transfer andother similar applications.

MTA pumps are suitable for applications involving elec-trical discharge machine tools, grinding machines,machining centers, cooling units, industrial washingmachines, filtering systems, etc.

The pumps feature ...

• low pressure

• open impeller

• filled PTFE bearing for high vibration resistance

• stainless steel impeller and shaft

• easy installation.

In addition, the two separate outlets of the MTAD two-chamber pump allow for high flexibility and ease of usein applications requiring flows different places.

Pumped liquidsThe pumps are suitable for pumping non-explosiveliquids, including water and water-soluble coolants andcutting lubricants.

PumpThe MTA pumps are one-chamber or two-chambercentrifugal pumps, of which the latter type, MTAD, hastwo separate outlets. Mounting flange dimensions areaccording to DIN 5440/JEM 1242.

MotorThe pump is fitted with a totally enclosed, fan-cooledmotor.

Enclosure type: TEFC (IP 54)Insulation class: F

Standard voltages

Other voltages are available on request.

MTAD 7/7 is available with plug connector, HAN 10 ES,on request.

Three-phase motors must be connected to a motorstarter in accordance with local regulations.

Operating conditionsLiquid temperature: +14°F to +194°F

Ambient temperatureMaximum +104°F (+40°C).

If the ambient temperature exceeds +104°F (+40°C) or ifthe motor is located 3280 ft. (1000 m) above sea level,the motor output (P2) must be reduced due to the lowdensity and consequently low cooling effect of the air. Insuch cases, it may be necessary to use a motor with ahigher output.

Example:From the above figure appears that P2 must be reducedto 88% when the pump is installed 11,000 ft (3500 m)above sea level. At an ambient temperature of 156°F(70°C), P2 must be reduced to 80% of rated output.

Technical data MTA(D)

Type keyThe pump key on the pump nameplate indicateswhether the pump is a one-chamber or two-chamberpump. The pump nameplate also indicates flow rate andinstallation length.

Curve conditionsThe performance curves are based on the folllowingconditions:

Pumped liquid

Installation

The MTA pump is designed for vertical mounting in atank.

The distance between the bottom of the pump and thebottom of the tank must be at least 3/8” (10 mm). Thepumps are designed to provide full performance downto a level of L in. above the bottom of the pump, seebelow.

Maximum liquid level

To protect the motor from the pumped liquid, themaximum liquid level in the installation tank must be 3/4”below the top of the tank. See the figure below.

MTC

Product descriptionMTC is designed for pumping cooling lubricants formachine tools, condensate transfer and other purposes.

MTC is specially designed for applications offering onlylimited space for installation. Motor and pump form anintegral, compact unit consisting of few components.The pump is designed for medium pressure.

The pump can be used for applications involving lathes,grinding machines, machining centres, cooling units,industrial washing machines, filtering systems, swarfconveyors etc.

Pumped liquidsThin, clean, non-explosive liquids without abrasiveparticles or fibers. Both water and water-soluble cool-ants and cutting lubricants can be pumped.

PumpThe pump is a multistage, centrifugal pump withmechanical shaft seal. Mounting flange sizes accordingto DIN 5440. To meet specific depths of tanks orcontainers, the installation length of the pump can bevaried using empty chambers. Available variants arebased on the number of stages indicated in the dimen-sions and weights tables.

MotorThe pump is fitted with a totally enclosed, fan-cooledmotor.

Enclosure type: TEFC (IP 54)Insulation class: FStandard voltages, 60 Hz: 3 x 208 - 230/460 V


Operating conditionsLiquid temperature:

MTC 2/4 +32°F to +194°FMTC 8/12/16 +14°F to +194°F

Type key Installation

If the MTC 2/4 pump is installed horizontally, the motorstool drain hole must be closed with a 1/8 in. pipe plug.

To enable a very low liquid level of 1 1/2 in. (37mm) forMTC 2/4 and 1 5/8 in. (40mm) for MTC 8/12/16 above thebottom of the strainer, a priming screw is fitted belowthe bottom intermediate chamber. This protects thepump against dry running down to 7/8 in. (22mm) forMTC 2/4 and 1 in. (25mm) for MTC 8/12/16 above thebottom of the strainer.

Distance between pump and tank bottom must beminimum 1 inch (25mm).

Product descriptionSPK/CRK are designed for pumping cooling lubricantsfor machine tools, condensate transfer and otherpurposes.

The pumps are designed for low to high pressure and arevery flexible as to installation length.

The pumps can be used for applications involving EDMmachine tools, grinding machines, machining centers,cooling units, industrial washing machines, filteringsystems etc.


PumpThe pump is a multistage, centrifugal pump with amechanical shaft seal. Mounting flange sizes accordingto DIN 5540. To meet specific depths of tanks orcontainers, the installation length of the pump can bevaried using empty chambers and/or an extension pipe.

Available variants are based on the number of stagesindicated in the dimensions and weights tables.

Example: An SPK 1 pump with 8 impellers is availablewith installation lengths from SPK 1-8 to SPK 1-23(dimension B). Note: Empty chambers may cause pressure loss.

I-versionAs standard the SPK/CRK pumps are available as I-version called SPKI/CRKI. All parts of SPKI/CRKI pumps incontact with the pumped liquid are made of stainlesssteel AISI 316 or 316LN.

MotorElectrical Data

Other voltages available on request.

Operating conditionsLiquid temperature: +14°F to +194°F (-10°C to +90°C).



Example:From the above figure appears that P2 must be reducedto 88% when the pump is installed 11,000 ft (3500 m)above sea level. At an ambient temperature of 156°F(70°C) P2 must be reduced to 80% of rated output.

Extension pipeAll SPK pumps are available with an extension pipe. Theextension pipe is available in various lengths enablinginstallation lengths up to 39 5/8 in. (1005 mm).

CRK 2 and CRK 4 pumps can be extended by means ofempty chambers enabling installation lengths up to 395/8 in. (1005 mm).

SPK, CRK 2/4 Installation

If the SPK pump is installed horizontally, the motor stooldrain hole must be closed.

The pumps are designed to provide full performancedown to a level of A in. above the bottom of the strainer.

At a liquid level between A and B in. above the bottom ofthe strainer, the built-in priming screw will protect thepump against dry running.

Loss curves for CRK 8 and CRK 16

Pressure loss in pumps with empty chambers

In pumps with empty chambers, there will be one or twochambers with a bearing. These chambers will have apressure loss which must be deducted from the perform-ance curves. The pressure loss can be found on thecurves below.

The number of empty chambers with bearing is found inthe table at the bottom of the page.

Curve 1 = Pumps with one empty chamber with bearing

Curve 2 = Pumps with two empty chambers with bearing

General data MTR

Product descriptionMTR is designed for pumping cooling lubricants formachine tools, condensate transfer and other purposes.

MTR is a strong and sturdy pump, designed for mediumto high pressure and large flows.

The pumps can be used for applications involving sparkmachine tools, grinding machines, machining centers,cooling units, industrial washing machines, filteringsystems etc.


PumpThe pump is a multistage, centrifugal pump withmechanical shaft seal. Mounting flange sizes accordingto DIN 5440. To meet specific depths of tanks orcontainers, the installation length of the pump can bevaried using empty chambers.
