Fraction, Decimal, and Simplified Details

One unique aspect of Giant’s documentation is the focus on precision measurement—fractions and decimals are central to the description of pumps like the GXH2525A-112H. The pump consists of parts where a fraction (like 7/8" shaft) must often be converted into decimal form during repair or replacement.

For example, the 7/8" shaft is equivalent to a decimal point value of 0.875. By converting fractions, using a calculator, and then multiplying or dividing, technicians can ensure a proper fit. This method of converting fractions into decimal form is a simplified process that can be applied across the complete line of Giant pumps.

One method used is to divide the numerator by the denominator—for example, enter 7 ÷ 8 into a calculator. The result, 0.875, is the correct decimal. This type of conversion is critical for applications that require precision in connection and operation.

Designed for High Pressure Systems

The GXH2525A-112H Giant Pump is more than just a replacement—it is a solution built for high pressure applications up to 2,650 PSI at 2.5 GPM. Its operation is designed around efficient plunger pump technology, with radial-axial design to maximize power transfer and minimize wear.

Pumps of this type are commonly used across many industries—from residential cleaning to commercial systems. The GXH2525A-112H has been determined as the go-to item when completing a repair on Ex-Cell and DeWalt models, making it the most widely trusted option on the market.

Components and Accessories

Every GXH2525A-112H signup kit offers a full line of accessories and parts to ensure easy installation:

• Built-in adjustable unloader for consistent high pressure control.

• Thermal relief valve for safety.

• Chemical injector for added applications.

• 3/16 drive key for required assembly.

• Inlet screen washer to prevent debris from entering the pump.

This item is fully simplified, making it straightforward to add to your cart and order with confidence.

Applications Across Industries

The GXH2525A-112H is widely used in many industries, from pressure washing to light industrial systems. It is particularly suitable for consumer-grade pressure washers by DeWalt and Ex-Cell, but it also has crossover applications where 7/8" shaft configurations are required.

• Residential: Great for homeowners needing a replacement pump that can handle high pressure jobs.

• Commercial: Used by contractors who rely on efficient pumps for daily operation.

• Industrial: Fits systems where high pressure plunger pump technology is required.

Simplified Math, Simplified Install

To illustrate the importance of precision, let’s take an example. If the volume requirement of your washer is 2.5 GPM, and the pump is rated at 2,650 PSI, you can multiply these values to calculate horsepower needs. Completing the calculation:

Horsepower = (PSI × GPM) ÷ 1450
= (2650 × 2.5) ÷ 1450
= 6.5 GHP

This simplified method, which involves multiplying, dividing, and sometimes subtracting, demonstrates why a calculator is essential in industries that rely on precise numbers.

By following such a method, signup steps for replacement pumps become easier, ensuring each item you add is the correct fit.

Completing the Installation

Installation of the GXH2525A-112H is straightforward:

1. Remove the old Oil-Free Strap pump.

2. Add the new GXH2525A-112H to the Honda GC Series Engine crankshaft.

3. Secure with the included drive key and handle all bolts with care.

4. Attach inlet and discharge ports using the included fittings.

5. Test operation under high pressure to confirm proper flow and volume.

This signup process has been simplified and documented in the included illustrated description for view and review.

Value and Cost Efficiency

The GXH2525A-112H Giant Pump offers excellent value compared to other pumps in the same category. While not the lowest cost option, it is not overly expensive when compared to the solutions it provides in durability and reliability.

By making the order once and using a pump that leaves fewer chances for breakdown, you save both time and money. The value is determined by reduced maintenance, improved operation, and long-term support from Giant’s complete line.
