SBE 5T and 5P pump

SBE 5P and 5T Submersible Pump

Centrifugal pump head and a long-life, brushless, DC, ball-bearing motor, for use on SBE 9plus, 16plus V2, 16plus-IM V2, 19plus V2, and 25plus CTDs.

The SBE 5T / 5P pump is a modular component on several Sea-Bird CTD packages. The 5T / 5P is standard equipment on the SBE 9plus CTD and 25 / 25plus Sealogger CTD, and optional equipment on the SBE 16plus V2, 16plus-IM V2, and 19plus V2 SeaCAT CT(D) Recorders. The highly reliable pump flushes water through the conductivity cell at a constant rate, independent of the CTD’s motion, improving dynamic performance. Operational characteristics of the 5T and 5P are identical, but the housings and depth ratings differ (5T titanium housing to 10,500 m; 5P plastic housing to 600 m).

The pump may also be suitable for custom applications, where pressure heads are less than 300 cm of water and flow rates are less than 100 ml/sec.

FEATURES

  • Centrifugal pump head.
  • Long-life, brushless, DC, ball-bearing motor.
  • Pump impeller and electric drive motor coupled magnetically through housing, providing high reliability by eliminating moving seals.
  • Pumping rates and motor current for various applications.
  • Five-year limited warranty.

OPTIONS

  • Voltage/power and RPM selections – Pump is configured by selecting voltage range, and one of several motor speed options (1300, 2000, 3000, and 4500 rpm speeds have been established to meet various flow requirements; other speeds can be set by adjusting a potentiometer). Typical settings include:
    • #3 winding, 10-18 VDC, 2000 rpm – typical for SBE 16plus V2, 16plus-IM V2, or 19plus V2 with pumped auxiliary sensor(s), and for SBE 25plus
    • #3 winding, 10-18 VDC, 3000 rpm – typical for SBE 9plus
    • #3 winding, 6-16 VDC, 2000 rpm – typical for SBE 25
  • Plastic (600 m) or titanium (10,500 m) housing.
  • XSG or wet-pluggable MCBH connector.

OPERATION

Motor speed and pumping rate remain nearly constant over the entire input voltage range (< 1% change in speed for a 1-volt change in supply voltage). The unrestricted flow rate with no head is 100 ml/sec * at 2000 rpm. Flow changes are nearly linear with speed changes. With unlimited power supply current, turn-on surge is 1.8 A * (maximum), which drops to steady state in 0.25 sec *. If power supply current is limited to 200 mA *, the motor comes up to speed in 0.30 sec *. A series diode is installed in the input power line to prevent damage if wires are accidentally reversed. Pumping rates and motor current for various applications are shown below.

What are the recommended practices for connectors - mating and unmating, cleaning corrosion, and replacing?

Mating and Unmating Connectors:

It is important to prepare and mate connectors correctly, both in terms of the costs to repair them and to preserve data quality. Leaking connectors cause noisy data and even potential system shutdowns. Application Note 57: Connector Care and Cable Installation describes the proper care and installation of connectors for Sea-Bird instruments. The Application Note covers connector cleaning and cable or dummy plug installation, locking sleeve installation, and cold weather tips.

Checking for Leakage and Cleaning Corrosion on Connectors:

If there has been leakage, it will show up as green-colored corrosion product. Performing the following steps can usually reverse the effect of the leak:

  1. Thoroughly clean the connector with water, followed by alcohol.
  2. Give the connector surfaces a light coating of silicon grease.

Re-mate the connectors properly — see Application Note 57: Connector Care and Cable Installation and 9-minute video covering O-ring, connector, and cable maintenance.

Replacing Connectors:

  • The main concern when replacing a bulkhead connector is that the o-rings on the connector and end cap must be prepared and installed correctly; if they are not, the instrument will flood. See the question below for general procedure on handling o-rings.
  • Use a thread-locking compound on the connector threads to prevent the new connector from loosening, which could also lead to flooding.
  • If the cell guard must be removed to open the instrument, take extra care not to break the glass conductivity cell.

Order SBE 5T (titanium) or SBE 5P (plastic) pump. Spares & Accessories for both are listed together at the bottom of this page.

PART # DESCRIPTION NOTES
05T Titanium Submersible Pump - Constant speed, centrifugal impeller, brushless DC motor, 10,500 m titanium housing. Includes complete documentation.

SBE 5T is standard pump supplied with SBE 9plus CTD or aluminum SBE 25 or 25plus CTD to provide pumped conductivity; also provides for other pumped sensors — dissolved oxygen, etc. SBE 5T is supplied optionally with 16plus V2, 16plus-IM V2, or 19plus V2 if system includes dissolved oxygen &/or other pumped sensors.

  • For pump with 600 m plastic housing & with same operational characteristics, order SBE 5P (below) instead (standard pump supplied with plastic SBE 25 or 25plus CTD; optional pump supplied with plastic SBE 16plus V2, 16plus-IM V2, or 19plus V2 if system includes auxiliary pumped sensor(s)).
  • For use on 16plus V2, 16plus-IM V2, or 19plus V2 if system does not include any auxiliary pumped sensors, order less powerful SBE 5M instead (available in plastic or titanium housing).
SBE 5T Connector Selections — MUST SELECT ONE
05T.21xxx XSG connector Wet-pluggable connectors may be mated in wet conditions. Their pins do not need to be dried before mating. By design, water on connector pins is forced out as connector is mated. However, they must not be mated or un-mated while submerged. Wet-pluggable connectors have a non-conducting guide pin to assist pin alignment & require less force to mate, making them easier to mate reliably under dark or cold conditions, compared to XSG/AG connectors. Like XSG/AG connectors, wet-pluggables need proper lubrication & require care during use to avoid trapping water in sockets.
