Argo-Hytos Pumps
Argo-Hytos external gear pumps cover displacements from 0.25 to 71 cm³/rev in two lines:
the GP1, GP2 and GP3 High Performance pumps, rated up to 250 bar continuous, and the GP0L, GP1L, GP2L and GP3L Lightline pumps for circuits with lower operating pressures, rated up to 200 or 230 bar.
All High Performance pumps use hydraulic axial clearance compensation to improve efficiency and reduce noise, with volumetric efficiency of 92–98%. They are available with SAE, ISO and DIN flanges, a choice of shafts and port connections, and can be combined into multiple pump units.
Argo-Hytos Gear Pump Range
High Performance Gear Pumps
- GP1: Displacements from 1.0 to 9.8 cm³/rev, with flange, cover and body in aluminium alloy. Continuous pressure is 250 bar on smaller sizes, falling to 120 bar on the 9.8 cm³/rev size, with speeds from 750 up to 3,500 rpm depending on size and a maximum flow of up to 18.6 l/min. BSPP, UNF and DIN 8901/8902 flanged port options, and a special design for Argo-Hytos SMA 05 hydraulic units.
- GP2: Displacements from 4.5 to 32 cm³/rev, with cast iron flange and cover and an aluminium alloy body. A 12-tooth gear keeps noise levels low. Continuous pressure is 250 bar on smaller sizes, falling to 120 bar on the 32 cm³/rev size, with speeds from 650 to 3,500 rpm and a maximum flow of up to 61 l/min. BSPP, UNF, DIN 8901/8902 and cross-pattern flanged port options.
- GP3: Displacements from 22.5 to 60 cm³/rev, with grey cast iron flange and cover and an aluminium alloy body. Continuous pressure is 250 bar on smaller sizes, falling to 150 bar on the 60 cm³/rev size, with speeds from 650 to 3,000 rpm and a maximum flow of up to 99.8 l/min. Port options include BSPP, DIN 8901/8902 flanged fittings, SAE flanges with UNC or metric threads and cross-pattern flanges. A version with a front-end bearing is available for drives that apply a load to the pump shaft.
Lightline Gear Pumps
- GP0L, GP1L, GP2L and GP3L: Single pumps for circuits with lower operating pressures. GP0L covers 0.25–0.80 cm³/rev at up to 200 bar and up to 7,000 rpm; GP1L 0.8–8.0 cm³/rev, GP2L 3.0–30 cm³/rev and GP3L 20–71 cm³/rev, all at up to 230 bar. Nominal flows at 1,500 rpm run from 0.35 l/min (GP0L) to 98 l/min (GP3L). Lightline pumps are not designed to be combined into multiple pump units.
All pumps run on mineral hydraulic oils (HL, HLP to DIN 51524) and environmentally friendly vegetable oil-based fluids. Further sizes, shafts, flanges and port configurations are available beyond those listed here; our team can help with any Argo-Hytos pump you need.
