GEAR PUMPS R65

Product catalog summary

Overview

This document provides technical information on the R65 series gear pumps manufactured by RICKMEIER GmbH. It covers flow rates, power input, pressure differences, mechanical design features, and dimensional data for various pump sizes.

Flow Rate and Power Input Specifications

The flow rates and power inputs for each pump size in the R65 series are presented as functions of the pressure difference between the suction and pressure ports. The data is based on a standard operating speed of 1450 rpm and a kinematic viscosity of 33 mm²/s.

Key points include:

Flow rate is approximately proportional to pump speed, allowing conversion for different speeds.
Power consumption adjustments for different speeds and viscosities should follow the conversion rules detailed in the company’s "General Technical Information."
Customized pump versions are available upon request.
An optional pressure relief valve can be adjusted by turning the spindle counter-clockwise to increase the valve opening pressure.

Performance Charts and Parameters

The document includes performance charts showing:

Flow rate (dm³/min) versus pressure difference (bar) for various pump sizes.
Power input (kW) versus pressure difference (bar) at the standard speed and viscosity.

Additional notes on tolerances:

Flow rate tolerances are specified according to VDMA 24284 standards, with different tolerance percentages depending on flow rate ranges.
Motor power requirement is calculated as 1.2 times the power input to account for efficiency and losses.

Mechanical Design and Options

The standard design features include:

Mechanical seal (Gleitringdichtung) for reliable sealing.
Optional pressure relief valve to protect the system from overpressure.

The document provides connecting dimensions for the R65 series pumps, including flange sizes, shaft diameters, and mounting dimensions, facilitating integration into hydraulic systems.

Dimensional Data and Weights

Key dimensional parameters are listed for different pump sizes, including displacement volume (cm³), suction and pressure connection sizes, adjustment ranges for the pressure relief valve, and weights (kg). For example:

Displacement volumes range from approximately 4.0 to 130.2 cm³ depending on the model.
Pressure relief valve adjustment ranges vary from 1 to 25 bar depending on configuration.
Weights vary accordingly, with additional weight noted when the pressure relief valve is installed.

Critical Information and Recommendations

When selecting a pump size, consider the required flow rate and pressure difference to ensure proper power input and motor sizing.
Use the provided conversion guidelines for operating conditions differing from the standard speed and viscosity.
Consult the manufacturer for special versions or customizations.
Adjust the optional pressure relief valve carefully to match system pressure requirements.

Die Einstellung des optional erhàltlichen Druckbegrenzungs- ventils an der Pumpe ergibt bei Linksdrehung der Spindel eine Steigerung des Ventilöff- The flow rate and power input have been specified in the mapping on the side for each pump size of the R 65 design in dependence on the pressure difference between suction side and pressure side. The flow rate can be converted approximately in proportion to speed. To determine the power consumption fora different speed and/or kinematic viscosity we refer to the conversion rule in our "General Technical Information" section. Customized versions of the pumps are available on request. The setting of the pressure relief valve at the pump, which is available as an option, provides for an increase of the valve opening pressure by turning the spindle counter-clockwise. ■ Zahnradpumpen ■ Ventile ■ Sonderprodukte ■ Système RICKMEIER GmbH E-Mail [email protected] FÖrderstrombereich R65 (Drehzahl 1450 1/min, kinematische Viskositàt 33 mmVs) Flow rates R65 (speed 1450 rpm, kinematic viscosity 33 mnf/s) Druckdifferenz zwischen Saug- und Druckanschluss pressure difference between suction and pressure connection [bar] Leistungsbedarf R65 (Drehzahl 1450 1/min, kinematische Viskositàt 33 mnf/s) Power input R65 (speed 1450 rpm, kinematic viscosity 33 mnf/s) motor power =1,2' power input Druckdifferenz zwischen Saug- und Druckanschluss pressure difference between suction and pressure connection [bar]
