1. REXROTH Gear Pumps

1.1 AZPF Series (Fixed Displacement External Gear Pumps)

The AZPF series is a high-reliability fixed displacement external gear pump developed by REXROTH, featuring compact structure, low noise, and strong anti-pollution performance. It is widely used in industrial hydraulic systems, especially in occasions requiring stable oil supply and small installation space.

Model	Displacement (cm³/rev)	Maximum Pressure (bar)	Maximum Speed (rpm)	Control Mode	Typical Application
AZPF-11-005RCB20MB	5.5	250	1800	Fixed displacement	Industrial hydraulic stations
AZPF-10-016RCB20MB	16.0	250	2000	Fixed displacement	Small hydraulic equipment

1.2 PGF Series (Fixed Displacement External Gear Pumps)

The PGF series is a high-pressure fixed displacement gear pump with high volumetric efficiency and long service life. It adopts advanced gear processing technology, which can adapt to harsh working conditions and is suitable for medium and high-pressure hydraulic systems in machine tools and plastic machinery.

Model	Displacement (cm³/rev)	Maximum Pressure (bar)	Maximum Speed (rpm)	Control Mode	Housing Material
PGF2-22/045RE01VE4	45.0	210	2800	Fixed displacement	Cast iron
PGF2-22/025RE01VE4	25.0	210	3000	Fixed displacement	Cast iron

Note: The AZPF/PGF series also includes double pump configurations (e.g., AZPF-10-016 + AZPF-11-005) with combined displacement ranges from 11.5 cm³/rev to 61.0 cm³/rev.

2. Parker Gear Pumps

2.1 PGP511 Series (Fixed Displacement External Gear Pumps)

The PGP511 series is a high-pressure, low-noise fixed displacement external gear pump with aluminum housing and 12-tooth design, featuring compact structure and high efficiency. It is widely used in construction machinery, agricultural machinery and hydraulic power units.

Model	Displacement (cm³/rev)	Maximum Pressure (bar)	Maximum Speed (rpm)	Control Mode	Typical Application
PGP511A0080CK1H2ND5D4S	8.0	300	3500	Fixed displacement	Construction machinery
PGP511B0080CK1H2ND5D4S	8.0×2	300	3500	Fixed displacement (double pump)	Hydraulic power units

2.2 PGP610 Series (Fixed Displacement External Gear Pumps)

The PGP610 series is a medium-flow fixed displacement gear pump designed for medium-pressure systems, with high manufacturing precision and durability. It is suitable for port machinery, agricultural machinery and industrial hydraulic systems.

Model	Displacement (cm³/rev)	Maximum Pressure (bar)	Maximum Speed (rpm)	Noise Level (dB(A))	Housing Material
PGP610B0100CK1H2ND5D4S	10.0	280	3000	≤72	Aluminum alloy
PGP610A0150CK1H2ND5D4S	15.0	280	2800	≤75	Aluminum alloy

3. Nachi Gear Pumps

3.1 IPH Series (Fixed Displacement Internal Gear Pumps)

The IPH series is a high-efficiency, low-noise fixed displacement internal gear pump with patent axial and radial pressure compensation design. It has stable performance and long service life, suitable for small hydraulic systems and precision hydraulic equipment.

Model	Displacement (cm³/rev)	Maximum Pressure (bar)	Maximum Speed (rpm)	Control Mode	Typical Application
IPH-2B-5-11	5.0	210	2500	Fixed displacement	Small hydraulic systems
IPH-3B-10-11	10.0	250	2200	Fixed displacement	Precision machine tools

3.2 IPH-G Series (Fixed Displacement Internal Gear Pumps)

The IPH-G series is an upgraded version of the IPH series, with higher pressure resistance and better volumetric efficiency. It adopts a two-section housing design, which is easy to maintain and suitable for high-precision hydraulic systems in metallurgical and plastic machinery.

Model	Displacement (cm³/rev)	Maximum Pressure (bar)	Maximum Speed (rpm)	Weight (kg)	Application
IPH-G-4B-20-11	20.0	250	2000	6.8	Plastic machinery
IPH-G-5B-32-11	32.0	250	1800	10.5	Metallurgical equipment

Note: The IPH series also includes double pump configurations (e.g., IPH-2B-5-11 + IPH-3B-10-11) with combined displacement ranges from 15.0 cm³/rev to 42.0 cm³/rev.
