🛁 ESPA Tiper0 90M Whirlpool Bath Pump – 1 HP (0.75 kW) Self-Draining

Precision-engineered hydromassage pump with self-draining technology for effortless whirlpool bath performance

💧 Product Overview

The ESPA Tiper0 90M is a single-speed centrifugal pump purpose-built for whirlpool bath and hydromassage systems. Delivering 0.75 kW (1 HP) of output power, this compact yet capable pump provides strong, consistent water flow through your bath jets, creating a satisfying hydrotherapy experience every time you step into the tub.

What sets the Tiper0 90M apart is its self-draining wet end design. After each use, the pump drains automatically by gravity — no additional drain connections or manual intervention required. This helps prevent stagnant water build-up inside the pump body, reducing the risk of bacterial growth and extending the pump’s working life.

Manufactured by ESPA in Banyoles, Spain, the Tiper0 90M features a robust technopolymer wet end, an aluminium motor casing, and a stainless steel shaft. It operates on standard UK 230V/50Hz single-phase supply and is designed for continuous duty with built-in thermal overload protection. The pump uses 2¼” male BSP threaded connections and is compatible with pneumatic or electronic control actuation.

🔗 Compatibility Guide

Port Connections:

Connection	Specification
Suction Port	2¼” Male BSP thread
Discharge Port	2¼” Male BSP thread
Thread Type	Male BSP

📍 Important: ESPA pumps use BSP (British Standard Pipe) threads on the port connections. Ensure that the correct unions are being used for your plumbing system. Unions are not supplied with the pump and must be purchased separately.

Compatible Union Options (sold separately):

• 1.5″ socket tailpiece for 1.5″ pipe connections
• 50 mm socket tailpiece for metric pipe connections
• 32 mm tee tailpiece for metric pipe connections
• 1″ tee tailpiece for imperial pipe connections

Motor Style:

📍 This pump features a smooth body (American style) motor profile. Verify your existing pump’s motor style and mounting dimensions when replacing.

Control Compatibility:

This pump can be operated via:

• Pneumatic actuation (requires an air switch or pneumatic control box, sold separately)
• Electronic actuation (requires a compatible electronic control box)

⚠️ Note: ESPA Tiper pumps may also carry alternative manufacturer labelling, such as “Bombas Electricas.” If your existing pump has different branding but matches the Tiper0 90M specifications, it may be the same unit.

🛠️ Installation Requirements

Mounting:

Requirement	Specification
Installation Location	Indoor use only
Mounting Position	Horizontal, on a solid level base
Fixing	Secure with bolts through mounting holes in pump base
Ventilation	Ensure motor can self-ventilate with dry airflow
Flood Protection	Install in a location safe from possible flooding

Plumbing:

Connection	Size
Suction	2¼” Male BSP
Discharge	2¼” Male BSP
Union Type	BSP threaded (unions sold separately)

Suction Pipe Requirements:

• Diameter equal to or greater than the pump inlet
• Maintain a minimum 2% ascending slope to prevent air pockets
• Keep the suction pipe as short as possible

Discharge Pipe Requirements:

• Diameter equal to or greater than the pump outlet to reduce friction losses
• Pipes must be independently supported — never rest pipe weight on the pump

Installation Notes:

⚠️ The pump must never be run dry — this will cause seal damage and void the warranty.

⚠️ Ensure the hydromassage system includes a minimum water level detection device to prevent dry running.

⚠️ Verify that the motor shaft rotates freely before first start-up.

⚠️ The motor rotation direction should be clockwise when viewed from the fan end.

⚠️ After starting, verify that the absorbed current is equal to or less than the value shown on the nameplate (3.7 A).

🔄 Maintenance Guide

Routine Maintenance:

Task	Frequency	Notes
Visual inspection for leaks	Monthly	Check around seal area and union connections
Check union tightness	Monthly	Retighten if any weeping is noticed
Verify motor ventilation	Quarterly	Ensure air vents are clear of dust and debris
Check amperage draw	Annually	Should read 3.7 A or less at rated voltage
Clean pump exterior	As needed	Wipe with a damp cloth — no harsh chemicals
Check mounting bolt tightness	Quarterly	Retighten if vibration has loosened bolts

💡 Tip: ESPA states that under normal conditions, these pumps are maintenance-free. However, periodic visual checks are recommended to catch potential issues early.

Warning Signs — Consider Replacement If:

• Unusual noise (grinding, screeching, or knocking)
• Water leaking from the mechanical seal area
• Motor trips the circuit breaker or thermal protection repeatedly
• Noticeable reduction in water flow through jets
• Motor runs excessively hot or fails to start

Mechanical Seal:

Seal Detail	Specification
Seal Type	Mechanical seal
Seal Materials	Graphite and aluminium oxide

⚠️ Replace the mechanical seal at the first sign of leakage. In the event of a fault, repairs should only be carried out by an authorised service agent.

Extended Inactivity:

If the pump will not be used for an extended period, ESPA recommends removing it from the installation, draining it fully, and storing it in a dry, well-ventilated location at temperatures between -10°C and 50°C.
