Selecting the right air-operated double-diaphragm pump starts with understanding the pump model number. At SANDPIPER, pump nomenclature is a standardized system that defines the exact configuration of a pump, including size, materials, valve type, porting, and options. This system helps eliminate guesswork, speeds up communication, and supports accurate pump selection, service, and replacement.
This article explains what nomenclature is, why it matters, and how SANDPIPER uses three generations of nomenclature across its product lines.
What Is Pump Nomenclature?
Nomenclature is a structured naming system used to identify complex industrial equipment. In pumping applications, nomenclature assigns meaning to each character in a model number so that every pump can be uniquely identified.
Rather than relying on informal product names, SANDPIPER pump model numbers communicate exact specifications. This allows distributors, maintenance teams, and SANDPIPER technical experts to reference the same pump configuration without ambiguity.
Why SANDPIPER Uses Pump Nomenclature
1. Universality
SANDPIPER model numbers are recognized globally. They avoid regional terminology and language differences, making it easier for teams across facilities and geographies to reference the same pump accurately.
2. Precision
A common name like “heavy-duty ball valve pump” can describe multiple sizes, materials, and configurations. A SANDPIPER model number removes that uncertainty by identifying the specific pump design, wetted materials, diaphragm materials, porting, and construction.
3. Organization
Nomenclature also reflects how pumps relate to one another. Pumps that share platform identifiers or design levels are closely related in performance and configuration, which helps users compare options and manage fleets of pumps more effectively.
How to Read SANDPIPER Pump Nomenclature
As SANDPIPER product lines have expanded, nomenclature has evolved. Today, SANDPIPER uses three primary generations of nomenclature, each aligned with specific pump families and applications.
Generation 1 Nomenclature
Generation 1 nomenclature is the original SANDPIPER model number structure and is still used for select heavy-duty product lines. This includes Heavy-Duty Ball Valve pumps designed for fluids with settling, suspended, or floating solids.
A representative example is the 1 ½ Heavy-Duty Metallic Ball Valve pump. The model number structure identifies the pump series, pump design, size, discharge porting position, diaphragm and check valve materials, design level, and construction. Each section of the model number corresponds directly to a defined pump attribute shown in the nomenclature diagram.
This structure allows maintenance teams to confirm whether a pump is aluminum, cast iron, or stainless steel, what elastomers are used, and how the pump is ported, all before opening a service manual.
Generation 2 Nomenclature
Standard Duty Non-Metallic Pumps
Generation 2 nomenclature was introduced for traditional standard duty air-operated diaphragm pumps, including non-metallic ball valve designs used across a wide range of industries.
The S05 Non-Metallic Standard Duty pump is a clear example. Its nomenclature begins with the SANDPIPER brand identifier and pump size, followed by codes that define check valve type, design level, wetted materials such as polypropylene or PVDF, diaphragm and check valve materials, porting options, pump style, and available kits.
For users, this means a single model number communicates whether the pump is conductive or non-conductive, NPT or BSP ported, center or inline ported, and what elastomers are installed.
Generation 3 Nomenclature
Containment Duty Pumps With Advanced Features
Generation 3 nomenclature was introduced as SANDPIPER expanded into new platforms with added features and configurations. This generation supports pumps with containment housings, leak detection options, and flange connections.
The SANDPIPER EvolutionX 1" pump uses this updated nomenclature system. The model number identifies pump size, check valve type, design level, wetted materials, diaphragm and check valve combinations, valve seat materials, porting style such as ANSI or DIN flanges, and containment or leak detection options.
This expanded nomenclature allows SANDPIPER to clearly define pumps built for containment applications where protection of personnel, the environment, and equipment is required.
Why Understanding Nomenclature Matters in the Field
Understanding pump nomenclature helps ensure the correct pump is specified during new installations. A properly identified model number confirms compatibility with the application, fluid, and operating conditions before the pump arrives on site.
It also helps reduce downtime and service delays. When a maintenance manager can reference a complete model number, replacement parts, service kits, and technical support requests move faster and with fewer errors.
How SANDPIPER Supports Pump Selection and Service
Customers do not need to memorize nomenclature systems to work with SANDPIPER. Local SANDPIPER distributors and technical teams use model numbers to guide pump selection, service recommendations, and troubleshooting.
Providing the full pump model number from the nameplate allows SANDPIPER teams to support customers throughout the pump lifecycle, from initial selection to ongoing maintenance.
Take the Next Step
If you are identifying an existing pump or selecting a new air-operated diaphragm pump, start with the model number. Referencing the correct nomenclature ensures the right pump, parts, and support are aligned with your application.
