AQM 80

High-pressure triplex plunger pump AQM 80, designed for output up to 160 kW, reaching pressures up to 810 bar and flow rates up to 220 l/min, delivers reliable performance for a wide range of industrial applications – cleaning of technologies, tanks, reservoirs, pipelines and sewers, fluid transfer, or as a pressure source for forming machines, mining units, presses, and other hydraulic systems.

In the standard version, the pump is equipped with an integral single-stage gearbox enabling, in most applications, direct drive of the pump by commonly available motors, and an internal oil cooler of the pump, which can be supplemented for higher outputs with a high-capacity external cooler.

Characteristics

the robust design makes the pump suitable for operation in the most demanding conditions
high reliability and long service life of the pump are ensured by the pump’s hydraulic section, which is made of high-quality stainless steel together with plungers featuring a special coating
strict separation of the spaces containing the pumped medium and the crankcase oil filling leads to higher operational reliability of the pump and reduced maintenance requirements
long service intervals are a key prerequisite for low operating costs
pumped medium: mainly intended for water, oils, and slightly chemically aggressive media with mechanical contamination up to 0.1 mm. Following consultation with our development team, the pump can be adapted for nearly any liquid

Pump description

Mechanical section of the pump:

verified crank mechanism design
an integral component of the mechanical section of the pump is an integrated single-stage gearbox offering a wide range of gear ratios, which greatly simplifies pump adaptation to required parameters and subsequent connection to the chosen motor (electric, hydraulic, or internal combustion)
lubrication is ensured by oil mist and pressure-fed lubrication through a gear pump driven directly by the crankshaft
multiple design configurations
- the drive shaft can be configured for right- or left-hand outlet
- structurally, it can be modified for direct drive of the crankshaft from the driving machine, allowing radial loading of the output shaft (belt drive)
- integrated water cooling of the oil fill in the standard design
- for higher outputs, an efficient cooling system using an external cooling circuit and utilizing the pumped fluid can be added

Hydraulic part of the pump

optimized to meet the requirements for pressure, flow rate, and the pumped medium
resistant to corrosion and cavitation – all parts in contact with the pumped medium are made of at least ferromagnetic stainless steel
according to requirements, the hydraulic components can be manufactured from steels of various grades, and the pump can be structurally adapted for pumping almost any medium (chemically aggressive substances, highly viscous liquids, non-standard temperatures, mechanically contaminated fluids, etc.) – see the Custom Pump Manufacturing section for more information

Valve assemblies

the precision design ensures minimal system pulsation
designed for pneumatic shut-off of the suction valves to enable optional pump control

Pump seals

maintenance-free soft ring packing (rings with rope packing pressed by a spring)
the pumped fluid is used for cooling and flushing of the seals
for non-standard pumped media, the seal can be designed in a lip seal configuration

Plunger

a wide range of diameters meets all customer requirements
made of high-quality austenitic steel
extended service life is achieved through a combination of a highly hard, wear-resistant coating and high-quality surface finishing
