Product Description

ALP1 SERIES Gear Pump  Overview

The Marzocchi ALP1 is a compact, high‑pressure fixed‑displacement external gear pump designed for modern hydraulic systems requiring lightweight construction, high efficiency and reliable continuous performance. Built with a full‑aluminum body and hardened steel gear components, it delivers an excellent power‑to‑weight ratio, making it ideal for mobile equipment and industrial applications where space and efficiency are critical.

ALP1

Features and Benefits

  • Lightweight High‑Strength Aluminum Construction:
    The ALP1 features a rugged, corrosion‑resistant aluminum housing with precision‑machined covers and gear chambers, offering superior rigidity while keeping overall weight low compared to cast‑iron alternatives. This construction minimizes internal deflection at high pressures, ensuring stable flow and extended service life in demanding conditions.
  • High‑Efficiency Gear and Seal Design:
    Utilizing precision‑ground, hardened steel gears and high‑performance NBR/FKM seals, the pump maintains exceptional volumetric efficiency across its operating range. The optimized gear profile reduces flow pulsation and noise, while the pressure‑balanced sealing system prevents internal bypass, delivering consistent performance at pressures up to 250 bar continuous.
  • Compact Footprint and High‑Speed Capability:
    With displacements from 1.4 to 13.8 cc/rev and a maximum operating speed of 6,000 rpm, the ALP1 delivers high power density in a compact package. Its modular design supports SAE, EU and common European flange, shaft and port configurations, making it adaptable to a wide range of installation requirements.
  • Superior Pressure and Thermal Performance:
    Engineered for continuous working pressures up to 250 bar (peak 290 bar), the ALP1 handles high‑pressure circuits with smooth, reliable flow. Its balanced pressure compensation design reduces friction and wear, ensuring consistent mechanical efficiency even at elevated operating temperatures and duty cycles.
  • Versatile Mounting and Configuration Options:
    The series offers multiple shaft (keyed, splined), flange and port combinations (side/rear), including reversible rotation options, to suit both mobile and stationary applications. This unmatched flexibility allows for direct replacement of competing pumps and seamless integration into cramped chassis environments.

ALP1 Gear Pump  FAQ

1. What are ALP1 series gear pumps

The ALP1 is a high‑performance, fixed‑displacement external gear pump from Marzocchi’s ALP Series. Featuring a lightweight, high‑strength three‑piece aluminum construction, it is specifically engineered for compact hydraulic systems that demand a high power‑to‑weight ratio and reliable continuous performance, especially in mobile equipment and light‑duty industrial applications.

2. What makes the ALP1 different from standard gear pumps

The ALP1 is built for efficiency and light weight in applications where cast‑iron pumps add unnecessary mass:
  • Lightweight Aluminum Housing: Unlike cast‑iron pumps, the ALP1’s aluminum body drastically reduces overall system weight, improving vehicle payload and fuel efficiency without sacrificing structural rigidity.

  • High‑Efficiency Gear Profile: Precision‑ground, hardened steel gears with optimized tooth geometry reduce noise and flow pulsation, delivering higher volumetric efficiency than many standard cast‑iron alternatives.

  • Modular Mounting Versatility: Standard with multiple flange (SAE “A”, “B”, European), shaft, and port configurations, the ALP1 offers unmatched installation flexibility in space‑constrained environments.

3. What is the working pressure range of ALP1 pumps

The ALP1 is a compact high‑pressure specialist. Depending on the specific displacement, the series typically handles:

  • Continuous Pressure: Up to 250 bar (3,625 PSI).

  • Intermittent/Peak Pressure: Up to 290 bar (4,205 PSI).

This robust pressure rating makes the ALP1 ideal for powering lifting, actuation, and compact power unit systems on light‑to‑medium duty equipment.

4. Can ALP1 pumps replace other brands

Yes, the ALP1 is a high‑quality, versatile alternative to other premium compact gear pumps. It is often used as a replacement or upgrade for:

  • Other Marzocchi “01” series pumps

  • Casappa PLP series

  • Parker PGP/PGM series

  • Bosch Rexroth AZPF series

To ensure a successful swap, verify the Mounting Flange (SAE or European standard), Shaft Type (keyed, splined), and Displacement (cc/rev) to match your existing system.

5. What hydraulic oil is suitable for ALP1 gear pumps

To protect the hardened steel gears and high‑performance seals, the following is recommended:

  • Oil Type: Premium mineral‑based hydraulic fluids with strong Anti‑Wear (AW) additive packages.

  • Viscosity: Standard ISO VG32 to VG68. The optimal operating range is 15–100 cSt, though it can handle cold starts up to 400 cSt.

  • Filtration: Cleanliness is vital for long seal and gear life. A minimum filtration of ISO 4406 18/16/13 is recommended to prevent abrasive particles from damaging the internal components.

6. What is the typical speed range of ALP1 pumps

The ALP1 is designed for high‑speed operation. Its typical operating range is:

  • Minimum Speed: 300 rpm (for stable flow at low pressures)

  • Maximum Continuous Speed: Up to 3,000–4,000 rpm (model‑dependent)

  • Peak Speed: Up to 6,000 rpm (for intermittent use)

This high‑speed capability allows the pump to be directly driven by engine PTOs or electric motors without the need for complex reduction gearboxes.

FAQ

1.How does the variable displacement work?

The pump's flow is adjusted by changing the angle of an internal swash plate. As the swash plate angle changes, the stroke length of the pistons varies, which in turn changes the volume of fluid displaced per rotation, allowing the flow rate to adapt to the system's needs.
