HSS Series

The HSS-Series is a horizontal centrifugal pump with a cast iron body, a stainless steel pump head with a stainless steel pump cover, and is suitable for a wide range of applications. The machine is capable of providing reliable pressure. These pumps can operate with liquid temperatures up to 70 degrees Celsius and the new whirlpool design can reduce noise to a significant extent.

02 · PRODUCT TYPE / SERIES POSITION

Horizontal multistage stainless steel centrifugal pump family

HSS selection is based on the duty point, liquid, connection, electrical supply and installation conditions. The product image represents the series and is not assigned to one exact model.

The clean-water source configuration identifies the pump casing, impeller and diffuser as SUS304.

  • Select by flow and total head
  • Suction and discharge sizes vary by model
  • Review liquid and electrical supply

MODEL CONTROL

Nine models in the technical source

HSS-54/54T, 55/55T, 84/84T, 85/85T and 164T have separate data in the model table.

  • T identifies a three-phase version
  • Curves are reviewed at 50 Hz
  • Dimensions and electrical data are model-controlled

03 · EQUIPMENT APPLICATIONS

Application contexts that require duty-point review

These are equipment application contexts. They do not state that McKarlen designs or executes the complete system.

Clean-water supply and transfer

Select against flow, total head, suction conditions and operating schedule.

Industrial utility water

Review liquid, temperature, materials and operating point by model.

Pipeline pressure boosting

Consider HSS as pump equipment; system and control design remain with the responsible project parties.

HVAC circulation

Check actual flow, head, temperature and operating conditions.

Tank-to-tank transfer

Confirm water level, suction line, piping losses and installation arrangement.

Replacement duties

Compare duty point, connection, electrical supply, dimensions and service access.

04 · KEY TECHNICAL DATA

Data order and model boundaries remain controlled

Technical values are confirmed by model, the applicable 50 Hz curve and the actual operating conditions.

MODEL DATA

Keep each field within source scope

HSS-54/54T, 55/55T, 84/84T, 85/85T and 164T.

5. Connection — Confirm by model.
6. Liquid — clean water; review compatibility for other liquids
7. Temperature — Confirm by model, liquid and seal configuration.
8. Pressure — Confirm by model.
9. Materials — casing, impeller and diffuser SUS304 for the listed clean-water configuration
10. Installation and operating conditions — confirm by model and site
Data boundary: no numerical range is published for the complete HSS Series. Flow, head, power, speed, connection, temperature, pressure, voltage, current and unlisted component materials remain model-controlled.

05 · PERFORMANCE / DUTY RANGE

Flow and head must be checked on the selected model’s 50 Hz curve

Do not select HSS from pipe diameter or a single table maximum. Review the duty point, system losses, frequency and electrical configuration together.

Duty point + liquid + electrical supply

Total head combines static head and piping losses at design flow. The selected model must operate on the applicable curve under confirmed conditions.

50 HZ CURVES

HSS-54/54T, 55/55T, 84/84T, 85/85T

50 Hz curves for HSS-54, HSS-55, HSS-84 and HSS-85

Direct source extract; axes, units and curves are unchanged.

50 HZ CURVE

HSS-164T

50 Hz curve for HSS-164T

Direct source extract; confirm the curve revision during model selection.

Responsibility boundary: McKarlen supports equipment selection and product-data confirmation. System design, piping, electrical work, construction, installation and site commissioning remain with the responsible project parties.

06 · MATERIALS / CONFIGURATION

9. Materials — publish only the components named by the source

Material data for three components is not converted into a claim that the complete HSS Series is entirely SUS304.

COMPONENT 01

Pump casing

SUS304
Listed clean-water source configuration; confirm by model.

COMPONENT 02

Impeller

SUS304
Listed clean-water source configuration; confirm by model.

COMPONENT 03

Diffuser

SUS304
Listed clean-water source configuration; confirm by model.

Other components: Detailed materials are confirmed by component and model. Shaft, mechanical seal, sealing parts, fasteners and complete motor materials are not sufficiently sourced for a universal public claim. Confirm by model and liquid.

07 · INSTALLATION CONDITIONS

10. Installation and operating conditions — prepare correctly for a horizontal pump

McKarlen provides equipment-related guidance. System design and site execution remain with the responsible parties.

Suction conditionsReview water level, suction losses, priming conditions and the risk of air entering the pump.
Pipe supportPrevent piping loads and stress from being transferred directly to the suction or discharge connection.
Base and alignmentProvide a stable surface, service access and alignment in accordance with the selected model guidance.
Electrical and operationConfirm phase, voltage, frequency, motor protection, operating schedule and ventilation.
Do not run dry or use with an unreviewed liquid. Operating limits and startup sequence are confirmed from the selected model documentation.

08 · TECHNICAL DOCUMENTS

HSS documents are issued by model and revision

The old source PDF is not offered as a public download because it contains obsolete company identity and contact details.

Selection documents

Issued after the model and duty point are confirmed.

10 · SPARE PARTS, WARRANTY & AFTER-SALES

Support is based on model, configuration and operating conditions

Provide equipment photos, nameplate details, delivery records, duty point and observed condition for review.

Model-based spare parts

Identify parts from the model, configuration, equipment details and photos of the required component.

Warranty request

Review delivery records, operating conditions and the results of equipment inspection.

After-sales technical support

Equipment-related guidance, operating-data review and product documentation support.
