Galtech is specialized in the production of external gear pumps from Group 1, Group 2 and Group 3 sizes, divided into 29 displacements from 0.9 to 62cc and up to 320 bar maximum working pressure. Pumps are available with cast iron flanges and covers to reduce noise level. Each pump can be assembled with standard flanges (European, German or SAE) or with special ZF, Perkins and Renault). Tapered, straight or splined shafts are available. It is possible to supply rear covers with pressure relief valves and flow control valves. All standard pumps are preconfigured for multi pump buildup, using the coupling kits, available.
Multiple pumps are available in two or more configurations and can be assembled in standard tandem or short tandem (common or separate suction) and short tandem for high and low pressure (including low pressure pump unloading valve). The versatility of our pumps allows assembling multiple pumps using single pumps thru a simple operation of disassembly / assembly, using “flange connections and accessories” kits.
External gear motors available in Group 2 and Group 3 sizes, divided into 17 displacements from 4 to 61,1cc, up to 270 bars maximum working pressure and maximum speed up to 4000 rpm, and hydrostatic balanced to reduce axial slack. Gear motors are available in unidirectional and bi rotational versions. Reversible motors can be used in series circuit). Each motor is available with standard flanges (European, German or SAE) or with special ZF, Perkins and Renault. Tapered, straight or splined shaft. It is possible to assemble covers with two speed functions, and with pressure relief valve.
Directional control valves
Available with high tensile cast iron body and nickel plated spools, BSP ports from ¼” to 1”, UNF from SAE 6 to SAE 16. These valves can be assembled with several controls and positioning options, spools with different flow sensitivity settings.
Monobloc directional control valves
Available from 1 to 8 working sections, with flow up to 120 LPM and maximum working pressure up to 350 bars. Auxiliary valves can be assembled directly on directional control valve, such as anti-shock valves, anti-cavitation valves or both.
Sectional directional control valves
Available from 1 to 10 working sections, with flow up to 150 LPM and with maximum working pressure up to 380 bars. Characterized by compact overall dimensions, thanks to the free flow “Y” shaped core, low pressure drop and very low internal leakages. Every element is supplied with a built in check valve. Available for “series” and “parallel” circuits. Each work section can be equipped with port cartridges or auxiliary valves to control pressure, anti-shock valves, anti cavitation valves or combined. These valves can be assembled with inlet sections and intermediate elements with built-in pressure and flow controls.
Load-Sensing control valves
Proportional load sensing post-compensated valves GSL series with flow sharing technology, cast iron body and nickel-plated spools, flow up to 200 LPM and pressure up to 350 bars. Available with BSP connections up to 1” max, UNF up to SAE 16 max, configuration from 1 to 10 working sections and a wide range of controls: manual, remote manual, direct, pneumatic and hydraulic connection and electro-hydraulic proportional control where the piloting channels are located inside the work sections. The series GSL can be used with fixed displacement pumps and variable displacement pumps (load sensing).
