SPECK Pumpen (Circutec) Heat Transfer, Side Channel and Vacuum Pumps

Engineering catalog of SPECK Pumpen / Circutec (Roth, Germany): TOEG and TOEM heat transfer pumps, regenerative turbine pumps, ES boiler feed pumps, SK and ASK side channel pumps, V, VZ and VHC liquid ring vacuum pumps and UniVac units.

TOEG Heat Transfer Pumps with Mechanical Seal

TOEG centrifugal pumps circulate organic and synthetic thermal oils and hot water in DIN 4754 heat transfer plants. Versions: TOEGN on a bearing bracket, close-coupled TOEGA and inline TOEGI. The modular system uses bearing brackets 360 and 470, rated PN 16.

Thermal oil up to 350 °C
Hot water up to 160 °C
Nominal pressure PN 16
Bearing brackets 360 and 470

TOEM Heat Transfer Pumps with Magnetic Coupling

TOEM pumps replace the shaft seal with a magnetic coupling for thermal oil circulation. TOEMN, TOEMA and TOEMI versions belong to the same 6-series modular system as TOEG. Thermal oils from -100 to 350 °C, up to 400 °C on request; ATEX II 2GD.

Regenerative Turbine Pumps for High Head

Regenerative turbine (peripheral) pumps deliver high head at low flow: up to 115 m and up to 400 l/min at 50 Hz. They handle liquids with gas content and pump without pulsation. Magnetic coupling heat transfer versions run water up to 220 °C and oil up to 400 °C.

Head 7 to 115 m (50 Hz)
Flow up to 400 l/min
Oil up to 400 °C, water 220 °C
Vertical TM-201 – TM-701 series

ES Boiler Feed Pumps

ES horizontal multistage pumps of modular design deliver hot water in boiler systems. Hydraulically balanced impellers and external shaft bearings carry the load. Mechanical seal or stuffing box packing, nominal pressure PN 40 or PN 63.

Nominal pressure PN 40 and PN 63
Water up to 120 °C
Modular system with 4 sizes
Mechanical seal or gland packing

SK and ASK Side Channel Pumps

SK and ASK self-priming multistage pumps handle filling and draining and pump liquids with gas content. ASK adds an NPSH inducer stage with a radial impeller for media near boiling point. Head up to 400 m, flow up to 35 m³/h, PN 40.

Head 35 to 400 m (50 Hz)
Flow 2 to 35 m³/h
Thermal oil -100 to 350 °C
SKG, ASKG, SKM, ASKM series

V and VZ Liquid Ring Vacuum Pumps

Close-coupled liquid ring pumps of the V, VE, VG, VI, VN and VZ series extract gases, vapours and condensate with oil-free compression. Inlet pressure down to 33 mbar abs., down to 5 mbar with a gas ejector. Two-stage VZ is also available with a magnetic coupling.

Minimum 33 mbar abs.
Down to 5 mbar abs. with ejector
Flow up to 1600 m³/h
VI, VE, VG, VN series

VH, VHC and VU Base Plate Vacuum Pumps

VH, VHC and VU are liquid ring vacuum pumps in base plate design for process lines. The two-stage VHC series develops the VH range with 11 sizes and suction capacity from 110 to 1,600 m³/h. Base plate pumps carry ATEX 1G IIB and IIB+H2 type examination.

VHC modular system, 11 sizes
Suction 110 to 1,600 m³/h
Inlet pressure 33 mbar
ATEX 1G IIB+H2 versions

UniVac and BluSystems Vacuum Units

UniVac units combine liquid ring pumps, separator tank, condenser and an optional heat exchanger: UniVac-1 uses V pumps, UniVac-2 two-stage VZ pumps. BluSystems units serve wet and dry calibration of plastic profiles.

Selecting SPECK Pumpen Centrifugal, Regenerative Turbine and Boiler Feed Pumps

For DIN 4754 thermal oil and hot water circuits Circutec builds a modular system of 6 series: TOEG with mechanical seal and TOEM with magnetic coupling, on bearing brackets 360 and 470, PN 16. Thermal oils run from -100 to 350 °C, up to 400 °C on request.

For low flow at high head, regenerative turbine pumps reach up to 115 m and 400 l/min without pulsation and with gas content.

ES boiler feed pumps serve boiler systems (PN 40 and PN 63, 4 sizes). SK and ASK side channel pumps are self-priming for filling and draining duties; ASK with its NPSH inducer stage suits media near boiling point.

Selecting Liquid Ring Vacuum Pumps and Units

Circutec liquid ring pumps compress gas oil-free and reach 33 mbar abs., down to 5 mbar with a gas ejector. Close-coupled V, VE, VG, VI, VN and VZ series cover flow up to 1600 m³/h; process lines use base plate VH and VU pumps and the two-stage VHC series with 11 sizes.

Ready-to-connect UniVac units add a separator tank, condenser and heat exchanger, while BluSystems units serve wet and dry calibration of plastic profiles.
