APLEX SC-115L Applications: Performance and Advantages
A. Typical Application Areas and Target Industries
The SC-115L, as a member of the SC Series, is designed for intermittent heavy-duty service.
Specific Application Areas (derived from APLEX/SC Series general information, applicable to SC-115L capabilities):
Oil & Gas: Crude oil gathering and pipeline transportation, Natural Gas Liquids (NGL) transfer, natural gas desulfurization and dehydration, produced water reinjection, oilfield services (well kill pumps, production pumps).
Horizontal Directional Drilling (HDD): Pumping drilling mud and water. Buckhorn Pumps explicitly lists the SC-65L for Vermeer 36x50 drilling rigs, and some SC-115L parts are common with SC-65L, indicating its applicability.
Industrial Cleaning: High-pressure water jet cleaning, factory equipment rinsing, vehicle washing.
Mining: Mine dewatering, bentonite slurry transfer.
Agriculture and Lawn Care (based on user query, supported by general high-pressure pump capabilities): Large-area spraying, pest and disease control, golf course maintenance, landscape care. (General capability, not explicitly listed in SC-115L documentation, but consistent with "intermittent duty high-pressure pump" characteristics).
Others: Steel mill descaling, hydrostatic testing, reverse osmosis, chemical processes.
The SC-115L, with its wide range of plunger size options and resulting flow/pressure combinations, along with optional material configurations, allows it to flexibly adapt to various intermittent duty tasks. It can handle everything from high-flow/medium-pressure applications (e.g., water transfer, large-area spraying) to medium-flow/higher-pressure applications (e.g., industrial cleaning, small HDD). Performance parameter table 3 shows that by changing plunger sizes, the SC-115L can adjust its performance output within the range of approximately 47 GPM @ 1815 PSI to approximately 231 GPM @ 1020 PSI. This flexibility, combined with optional fluid end materials, makes it more suitable for a wide range of applications than pumps with fixed performance points.
