Interpump Spare Parts & Components: Buyer's Guide

About Interpump: What the OEM Makes

Interpump is a specialist manufacturer of high-pressure plunger pumps and associated equipment for industrial, agricultural, and cleaning applications. The 3G Electric catalog lists 4,007 Interpump products across seven categories:

• Industrial Pumps — 736 SKUs; the core product line, covering triplex and multiplex plunger pumps from compact flange-mount units to motor-integrated assemblies
• Pressure Washers — 109 SKUs; cart and stationary units for professional cleaning
• Motor Pumps — 105 SKUs; pump-plus-motor assemblies ready for direct installation
• Spare Parts — 32 dedicated spare-part SKUs (seals, valves, heads, and sub-assemblies)
• Agriculture Pumps — 7 SKUs; field-spraying and irrigation duty
• Accessories — 6 SKUs; spray guns, nipples, and connection hardware
• Valves — 5 SKUs; unloader and bypass valves

Understanding which category your replacement part falls into is the first step toward selecting the correct SKU.

Key Product Lines and Representative Specifications

Interpump organises its industrial pump range by series prefix. The table below shows representative catalog models available through 3G Electric, illustrating the breadth of the range.

Note that physically similar pumps in the E1B and E1C series differ in rated shaft speed (1,450 rpm vs 1,750 rpm) and valve configuration — always verify both parameters before ordering a replacement pump head or seal kit.

How to Decode an Interpump Part Number

Interpump SKUs follow a structured alphanumeric convention. Breaking down the code correctly prevents ordering the wrong variant. Use this procedure:

1. Locate the nameplate. The pump's data plate carries the full model designation, serial number, rated flow (L/min), rated pressure (bar), and shaft speed (rpm). Photograph it before disassembly.
2. Identify the series prefix. The leading letters (e.g., E1B, E1C, C2W, WW, T) indicate the pump family and crankcase design.
3. Read the numeric block. The digits encode rated speed and displacement — for example, in E1B1810, the segment 18 relates to pressure class and 10 to flow class. Cross-reference against the OEM parts manual for your specific series.
4. Check the suffix. Suffixes such as R (right-hand rotation), L (left-hand rotation), V or BV (built-in bypass valve), FL.B3B14 (B3B14 flange), and DX (direct drive, right) define mounting and rotation. Mismatching a suffix is a common ordering error.
5. Confirm the SKU format. In the 3G Electric catalog, the ordering SKU appends a variant code after a hyphen (e.g., -000 for standard, -H001 or -H002 for motor-integrated assemblies). Provide the full SKU when requesting a quotation.
6. Cross-reference accessories. Spray guns and nozzles carry their own SKU series (e.g., ZP10X-000 for the GUN P10 with nipple, rated to 200 bar / 3,000 psi and 140 °C). Verify that accessory pressure and temperature ratings meet or exceed your system's operating envelope.

Compatibility Basics: Matching Parts to Your System

When sourcing Interpump spare parts, four parameters must align between the replacement part and the installed pump:

• Pressure rating (bar / psi / MPa). Catalog pumps range from 90 bar (pressure washers) up to 200 bar for industrial units. A seal kit rated for 150 bar must not be fitted to a 180 bar pump.
• Shaft speed (rpm). The E1B series runs at 1,450 rpm; the E1C series at 1,750 rpm; the E1E petrol-flange variant at 3,400 rpm. Plunger seals and bearings are sized for specific speed ranges.
• Rotation direction. Right-hand (R/DX) and left-hand (L) variants use mirrored crankshaft configurations. Check the suffix and confirm against the motor's output shaft rotation.
• Flange standard. Motor-coupled pumps specify a flange code (e.g., B3B14). Spare pump heads and crankcase assemblies must match the installed flange to avoid re-engineering the motor bracket.

For pressure-washer units such as the CLEANMATIC CL11 VARIOJET CART (SKU CL11VK-000), rated at 90 bar / 1,300 psi working pressure with a 120 bar / 1,750 psi maximum, ensure any replacement unloader valve or hose assembly is rated above the maximum — not merely the working — pressure.

Accessories and Spray Guns

Interpump's accessory range complements the pump line. The GUN P10 W/NIPPLE (SKU ZP10X-000) and the AUTOMATIC SPRAY GUN P10 (SKU ZP10-000) share identical hydraulic ratings:

• Max flow: 40 L/min (10.56 US gpm)
• Max pressure: 200 bar / 3,000 psi / 20 MPa
• Max temperature: 140 °C / 284 °F

The distinction between the two is the nipple fitting included with the ZP10X-000 variant. When ordering a replacement gun, confirm whether your existing lance assembly requires the nipple or uses a direct BSP/NPT connection.

How to Source Genuine Interpump Parts Through 3G Electric

1. Gather nameplate data. Record the full model code, serial number, rated pressure, flow, and shaft speed from the pump's data plate.
2. Search by SKU or model. Use the 3G Electric product catalog to locate the exact SKU. For spare-part sub-assemblies, search within the dedicated Spare Parts category (32 SKUs) as well as the broader Industrial Pumps range.
3. Request a quotation. All Interpump products are available to order; lead time is confirmed at quotation stage. Submit the full SKU, quantity, and any application notes (operating pressure, fluid type, ambient temperature).
4. Verify packaging and authenticity. Genuine Interpump parts ship in OEM-branded packaging with the part number printed on the label. Cross-check the label against the SKU provided in your order confirmation.
5. Plan for international logistics. 3G Electric manages customs documentation and worldwide delivery. Confirm Incoterms and estimated lead time at the quotation stage to align with your planned maintenance window.

Frequently Asked Questions

What product types does Interpump manufacture?

Interpump produces industrial pumps, pressure washers, motor pumps, spare parts, agriculture pumps, accessories, and valves. The 3G Electric catalog lists 4,007 Interpump SKUs across these seven categories, with industrial pumps accounting for 736 of them.

How do I identify the correct Interpump spare part number?

Start with the pump's nameplate: record the full model code, rated pressure (bar), flow (L/min), and shaft speed (rpm). Decode the series prefix, numeric block, and suffix (rotation, flange, valve options), then match to the full catalog SKU including the hyphenated variant code.

What is the maximum pressure available in the Interpump industrial pump range?

Based on the 3G Electric catalog, the highest-rated models reach 200 bar / 3,000 psi / 20 MPa — for example, the C2W2011 (SKU C2W2011-000) and the P10 spray gun accessories. Always verify the specific model's data plate before selecting replacement seals or valves.

Does rotation direction matter when ordering a replacement Interpump pump?

Yes. Interpump pumps are designated R (right-hand / DX) or L (left-hand) in the model suffix. Fitting the wrong rotation variant will misalign the crankshaft relative to the motor output shaft. Always confirm rotation direction from the nameplate before ordering.

Can I order Interpump spare parts for international delivery through 3G Electric?

Yes. 3G Electric supplies Interpump products worldwide, handling customs documentation and international logistics. All items are available to order; lead time and Incoterms are confirmed at the quotation stage — no stock claims are made prior to order confirmation.

What is the difference between the E1B and E1C pump series?

Both series share the same physical envelope (194.5 mm overall dimension, 5 kg weight) but differ in rated shaft speed: E1B runs at 1,450 rpm while E1C runs at 1,750 rpm. Seal kits, bearings, and valve assemblies are sized accordingly — the two series are not interchangeable.

Are Interpump spray guns compatible with all pump models?

Compatibility depends on pressure and flow ratings. The P10 gun range (ZP10-000, ZP10X-000) is rated to 200 bar / 3,000 psi and 40 L/min. Verify that your pump's rated pressure and flow fall within these limits, and confirm the inlet connection standard (BSP or NPT) matches your lance assembly.

How many dedicated spare-part SKUs does Interpump offer in the 3G Electric catalog?

The 3G Electric catalog lists 32 dedicated Interpump spare-part SKUs covering seals, valves, heads, and sub-assemblies. Additional replacement components may also be found within the broader Industrial Pumps and Accessories categories depending on the assembly type required.
