HIGHLAND HPV110 Variable Displacement Axial Piston Hydraulic Pump 42MPa 110ml/r for Combine Harvester Cold Climate
The HIGHLAND HPV110-MA-L-23 is a high-performance axial piston variable displacement hydraulic pump designed for closed circuit hydrostatic transmission systems in agricultural combine harvesters and heavy machinery. With 110 ml/r displacement, 42 MPa (420 bar) maximum pressure, and 97% volumetric efficiency, the HPV110 delivers reliable power transmission for the most demanding harvesting conditions. Built with low-temperature seals rated from -25°C to +85°C, this pump is engineered for cold-climate agricultural regions including Russia, Kazakhstan, Ukraine, and Northern Europe.
- Closed Circuit Hydrostatic Drive: Integrated charge pump circuit eliminates the need for a separate charge pump in many configurations, simplifying system design and reducing installation cost.
- 42 MPa High Pressure Capability: 35 MPa rated continuous pressure with 42 MPa peak capability ensures reliable performance even under heavy crop loads and tough terrain conditions.
- 97% Volumetric Efficiency: Precision-machined piston bores and optimized port plate timing deliver class-leading efficiency, reducing fuel consumption and heat generation in the hydraulic system.
- Cold Climate Ready: Standard equipped with double-lip FKM low-temperature shaft seals and wide-temperature-range hydraulic fluid compatibility. Reliable cold-start performance down to -25°C for Russian and Siberian harvesting seasons.
- Manual Adjustable Control (MA): Mechanical swashplate angle adjustment provides precise displacement control from zero to maximum. Simple, robust, and field-serviceable without specialized electronic diagnostic tools.
- Versatile Agricultural Application: Proven on combine harvesters (wheat, corn, soybean, rice), cotton harvesters, forage harvesters, and self-propelled sprayers. Compatible with Rostselmash, Gomselmash, and other CIS-manufactured harvesting equipment.
- ISO 9001:2015 Certified Quality: Every pump undergoes full-load pressure testing, volumetric efficiency verification, and noise level inspection before shipment. Test report included with each unit.

Q: Is the HPV110 a direct replacement for any OEM pump?
A: The HIGHLAND HPV110 is designed as a high-quality alternative for closed circuit hydrostatic transmission systems used in agricultural machinery. It is not a direct copy of any single OEM pump but is engineered to match or exceed the performance specifications required by combine harvester and agricultural equipment manufacturers. We provide detailed dimensional drawings and hydraulic schematics for integration support.
Q: What is the warranty period?
A: We provide a 12-month warranty from the date of shipment. The warranty covers manufacturing defects and material failures under normal operating conditions as specified in our technical documentation. Extended warranty options are available for bulk orders and fleet customers.
Q: How does the HPV110 perform in cold Russian winters?
A: The HPV110 is equipped with double-lip FKM low-temperature shaft seals rated for continuous operation from -25°C to +85°C. For cold starts in Siberian conditions (below -20°C), we recommend preheating the hydraulic oil to approximately 20-30°C before applying full load, and using ISO VG 22 or VG 32 low-viscosity hydraulic oil during winter operation.
Q: Can you provide left and right rotation versions?
A: Yes. The HPV110 is available in both Left (L) and Right (R) rotation. The model designation HPV110-MA-L-23 indicates Left rotation. Right rotation is available as HPV110-MA-R-23. Please confirm your required rotation direction when ordering.
Q: What control modes are available?
A: The HPV series offers three control options: MA (Manual Adjustable) for mechanical swashplate control, EP (Electro-Proportional) for electronic joystick or PLC-based control systems, and HD (Hydraulic Direct) for pilot-pressure-operated systems. MA control is the most popular for agricultural applications due to its simplicity and field-serviceability.
Q: What is the delivery time to Russia?
A: Stock items ship within 5-7 working days by air freight (5-7 days to Moscow, 7-10 days to Novosibirsk). Production orders typically require 15-20 days. Sea freight to Vladivostok or Saint Petersburg takes approximately 25-35 days. We work with logistics partners experienced in Russian customs clearance and can provide DDP shipping options upon request.
Q: Do you supply spare parts and service support?
A: Yes. We maintain a full inventory of HPV series spare parts including piston assemblies, cylinder blocks, valve plates, swash plates, shaft seals, and complete seal kits. All parts are available for immediate dispatch. We also provide technical service manuals, installation guides, and remote technical support.
Q: Do you accept sample orders for testing?
A: Absolutely. We accept sample orders of 1 piece for field testing and evaluation. Trial customers receive the same 12-month warranty and full technical support as volume buyers. Many of our long-term Russian distributor partnerships began with a single test unit.
Q: What are your accepted payment methods?
A: We accept T/T (bank wire transfer), L/C (Letter of Credit), and Western Union. For established customers, we offer flexible payment terms including 30% advance with 70% before shipment or 100% L/C at sight. We can discuss payment solutions suitable for your procurement process.
