QT42 QT52 QT62 Medium-Pressure Internal Gear Pump Range

Product Overview

The broader attributes list a 10–125 cc/rev range, rated pressure of 18 MPa or 180 bar, and maximum pressure of 21 MPa or 210 bar. Operating pressure is also recorded as 21 MPa. Exact values should be tied to the selected QT series and size.

Maximum-speed references are 1,200, 1,500, and 1,800 r/min, with QT450 and 42CrMo listed as materials. The product measures 17.2 × 17.2 × 31.2 cm, and the package is 18 × 18 × 32 cm at 24 kg gross.

Technical Specifications

Key Features

• Three QT Series References: QT42, QT52, and QT62 are grouped in one listing, but the ordered series and displacement must be specified. Do not assume identical interfaces across every version.
• 40–100 cc/rev Title Range: The title identifies 40–100 cc/rev, while the attribute range is 10–125 cc/rev. These ranges are not identical, so the inquiry should state one exact displacement and QT model. The confirmed quotation should supersede the general range descriptions for order control.
• 18 MPa Rated Pressure: Rated pressure is listed at 18 MPa and maximum pressure at 21 MPa. The operating-pressure entry also shows 21 MPa, creating a point that needs clarification. Define continuous and peak duty and obtain the applicable limits for the exact QT configuration.
• Hydrowork Replacement Positioning: The title presents these pumps as Hydrowork hydraulic internal gear pump replacements. That reference supports product discovery but does not prove universal interchangeability. Full original codes, displacement, rotation, shaft, mounting, and port dimensions are required for a reliable cross-check.
• Low-Noise, Long-Life Description: Low noise and long life are the qualitative features recorded in the source. The page does not provide acoustic test data or endurance results. If noise or operating life is a contractual requirement, request a defined test method and acceptance level for the selected pump.
• Material and Packing References: QT450 and 42CrMo are listed materials, and carton or wooden-box packaging is available. No component-level material allocation is provided. Confirm the exact material scope, packing method, final dimensions, and gross weight when those details affect inspection or transport planning.

Applications

This product page represents a replacement-oriented QT pump range rather than one fixed configuration. The following contexts are appropriate for evaluation only after the exact series, displacement, interfaces, speed, and pressure duty are confirmed.

• Hydrowork internal gear pump replacement checks using full original codes
• QT42 projects requiring an exact displacement within the offered range
• QT52 hydraulic circuits matched to confirmed pressure and speed
• QT62 replacement sourcing based on dimensional and interface verification
• Medium-pressure systems designed around an 18 MPa rated pump

Selection Guide

Choose the series and displacement together. Provide QT42, QT52, or QT62 plus the complete suffix and required cc/rev value. The title's 40–100 cc/rev range differs from the 10–125 cc/rev attribute range, so require the exact size, expected flow at speed, rated pressure, and maximum pressure on the technical confirmation.

For a Hydrowork replacement, compare the original nameplate, rotation, shaft, mounting pilot, bolt pattern, inlet and outlet specifications, and port orientation with the offered drawing. Also provide fluid, temperature, filtration, inlet conditions, drive speed, and duty cycle. Overall catalog dimensions are not enough to establish direct fit.

Ordering Information

MOQ is one set, and no public price is recorded. Send the selected QT42, QT52, or QT62 series, complete model code, quantity, displacement, flow target, speed, normal and peak pressure, rotation, shaft, mounting, ports, fluid, and Hydrowork reference. Confirm the applicable range, carton or wooden-box packing, final shipping data, and warranty wording; the source warranty field contains both one-year and six-month entries.

Frequently Asked Questions

Q: Which pump series are included in this listing?

A: The source names QT42, QT52, and QT62. It is a family listing, so buyers should select one series and provide the full model suffix and displacement. Do not place an order using only the three grouped series names.

Q: What displacement range is available?

A: The product title states 40–100 cc/rev, while the attributes show 10–125 cc/rev. Because the ranges differ, confirm the exact available displacement for the chosen QT42, QT52, or QT62 version and record it in the order.

Q: What pressure values does the source provide?

A: Rated pressure is 18 MPa, or 180 bar, and maximum pressure is 21 MPa, or 210 bar. The operating-pressure field also states 21 MPa. Ask for written clarification of continuous and peak duty for the selected model.

Q: Is this a guaranteed Hydrowork drop-in replacement?

A: The title describes Hydrowork replacement positioning, but it does not guarantee every model is a drop-in fit. Confirm the full original code, displacement, direction, shaft, mounting, ports, dimensions, speed, and pressure before approving interchangeability.

Q: What speed and packaging choices are listed?

A: Maximum-speed options are 1,200, 1,500, and 1,800 r/min. Packaging is listed as carton or wooden box, with a single package of 18 × 18 × 32 cm and 24 kg gross. Confirm both selections before shipment.
