Series 45 open circuit axial piston pumps

The Series 45 family of pumps are a high-performing and flexible option for new machine applications needing variable displacement open-circuit flow in the medium pressure range (up to 310 bar). With a full line of displacements, controls, and mounting options, the Series 45 modular design approach reduces your time to market and provides a more competitive, reliable product to your customers.

Optimized system design

When you equip your machine with Series 45 pumps, choosing valves and controls that are made to work together can truly optimize your machine. Series 45 pumps are PLUS+1® compliant and our electronic controls are ready to go with plug and play software using the Danfoss PLUS+1® GUIDE programming environnent. They are also the perfect match for PVG proportional valves, providing efficient and precise machine movement across a wide range of flow requirements.

A broad portfolio for maximum control

Series 45 pumps can be equipped with a broad range of control options. In addition to a full range of standard pressure compensation and load sensing controls, we offer many controls for today’s electrified systems needing electronic actuation or power management.

Our optimized Fan Drive Control (FDC) comes in a slim single spool package and is specifically engineered for ideal cost-effective regulation of fan speed in cooling, cleaning, and vacuum fan systems.

Electronic Displacement Control (EDC) – available exclusively on the K2-frame – is an excellent choice for simple and robust control of pump flow to machine functions. This control can reduce dependency on intermediate valves for motor applications, provide dynamic maximum displacement limitation for auxiliary flow functions, or provide power management for overload protection.

Electronic Torque Limiting (ETL) controls are a premium choice in the industry for managing of power or torque. Use these controls when you want to maximize productivity, minimize fuel consumption, or protect your system from overloading conditions. Not only can this system solution protect diesel engines from stalling, but it can also be used to limit current draw through electric motor inverters.

Unique features for unique customers

We understand that every customer is different and therefore your requirements are too. Series 45 helps meet the important and diverse needs of the mobile equipment market with features like a lead-free valve plates.
